Pulse amplitude modulation (PAM) is a modulation technique where the amplitude of pulses in a regularly timed sequence is varied according to the amplitude of the modulating signal. There are two types of PAM: single polarity PAM which adds a DC bias to ensure all pulses are positive, and double polarity PAM where pulses can be both positive and negative. PAM is generated by sampling the modulating signal at regular intervals and making each sample proportional to the amplitude of the modulating signal at the time of sampling. The amplitude of the PAM signal then carries the information contained in the modulating signal.

Amplitude modulation (AM) varies the amplitude of a carrier wave based on the instantaneous amplitude of a message signal. In AM, the frequency and phase of the carrier wave remain constant while the amplitude is varied by the message signal. The modulation index, m, indicates the degree of modulation and is defined as the ratio of the amplitude of the message signal to the carrier amplitude. An AM signal produces a carrier wave along with upper and lower sideband frequencies that contain the message information.

Modified Coverage Hole Detection Algorithm for Distributed WSNsidescitation
Wireless sensor networks (WSNs) are spatially
distributed sensors that find wide applications in various fields
such as environmental control, Medicine and Health care,
Military surveillance etc. The sensing and communication
within the network should be effective for such applications.
Holes are the voids created in the network when accidental
death of nodes is caused due to technical

coverage. The detection of the holes becomes essential after
the random deployment. The main objective of the work is to
detect the coverage holes using computational geometry
approach which uses co-ordinates of the sensors and to
implement it in the hardware. The communication range of a
node is considered to be equal to its sensing range. The protocol
is designed for irregular domain which is a real time scenario
and takes the help of two-hop neighbors’ of a node to detect
the hole around it. The proposed system also allows only few
nodes to initiate the detection algorithm so that the energy

This document provides an overview of diodes and semiconductors. It explains that semiconductors are made from elements that can form covalent bonds, sharing electrons.

Localization of Objects Using Cross-Correlation of Shadow Fading Noise and Co...Rana Basheer
When a radio transmitter is mobile, obstacles in the
radio path can cause temporal variation in Received Signal Strength Indicator (RSSI) measured by receivers due to multipath and shadow fading. While fading, in general, is detrimental to accurately localizing a target, fading correlation between adjacent receivers may be exploited to improve localization accuracy. However, multipath fading correlation is a short range phenomenon that rapidly falls to zero within a wavelength whereas,
shadow fading correlation is independent of signal wavelength and has longer range thereby making it suitable for localization with wireless transceivers that operate at shorter wavelength. Therefore,
this paper presents a novel wireless localization scheme that employs a combination of cross-correlation between shadow fading noise and copula technique to recursively estimate the location of a transmitter. A stochastic filter that models multipath fading as an Ornstein-Uhlenbeck process followed by a Generalized Auto Regressive Conditional Heteroskedasticity (GARCH) filtering is
proposed to extract shadow fading residuals from measured RSSI values. Subsequently, Student-T Copula function is used to create the log likelihood function, which acts as the cost function for localization, by combining spatial shadow fading correlation arising among adjacent receivers due to pedestrian traffic in the area. Maximum Likelihood Estimate (MLE) is used for position estimation as it inherits the statistical consistency and asymptotic
normality. The performance of our proposed localization method is validated over simulations and hardware experiments.

Powerful business model for fixed wireless data using outdoor antennas - PaperAndre Fourie
Paper presented at the 2nd Africa Radio Comms Conference in Johannesburg - Nov 2015
By Andre Fourie
The revenue that can be generated by an LTE base station is influenced by the quality of the signal received by the customer premise equipment (CPE). Most CPE come with omni-directional indoor antennas, but have provision for the connection to external antennas.
Substituting the indoor antennas for directional outdoor antennas has a marked effect on the data transfer speeds of the network. There are two reasons for this. Firstly, outdoor antennas are physically larger than their indoor counterparts and thus have a higher gain. The increase in antenna gain translates directly to an increase in received signal strength. The second advantage is that the outdoor antenna sits in an environment that has much better propagating properties than the indoor antenna. Tests have shown that data speeds 3-5 times faster are possible using external antennas compared to indoor antennas.
It is shown, using a primitive financial model that fairly large financial gains can be made by equipping CPE devices with external antennas.
This chapter discusses the transmission of binary data in communication systems. It covers digital codes such as ASCII and EBCDIC used to represent numerical and text data. Binary data can be transmitted serially by sending each bit one after the other. Asynchronous transmission includes start and stop bits with each data word, while synchronous transmission transmits words continuously in blocks separated by synchronization bits. Encoding methods like NRZ, RZ, and Manchester are used to represent digital signals compatible with transmission mediums.
In data communication,
Transmission media is a pathway that carries the information from sender to receiver.
We use different types of cables or waves to transmit data.
Data is transmitted normally through electrical or electromagnetic signals.
Synchronous optical networking (SONET) is a standardized digital communication protocol that is used to transmit a large volume of data over relatively long distances using a fiber optic medium. With SONET, multiple digital data streams are transferred at the same time over optical fiber using LEDs and laser beams.
Disadvantages And Disadvantages Of Wireless Networked And...Kimberly Jones
The document describes an implementation of the Bellman-Ford algorithm to find the shortest path routing from node U in a provided network diagram. The program outputs the routing table for node U after each iteration, showing the destination and number of hops. It runs for V-1 iterations, where V is the total number of vertices. The algorithm uses a relaxation formula to calculate the shortest path between each edge iteratively. By the final iteration, the optimal shortest paths from the source node U to all other nodes are determined. A Word document with screenshots explains how the program incorporates the Bellman-Ford algorithm and determines when the routing table is optimal.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
