Performance enhancement of wireless sensor network by using non-orthogonal mu...nooriasukmaningtyas
In this paper, we investigate a relaying wireless sensor network (WSN) with
the non-orthogonal multiple access (NOMA) and sensor node selection
schemes over rayleigh fading. Precisely, the system consists of two sensor
clusters, a sink node, and an amplify-and-forward (AF) relay. These sensors
applying the NOMA and sensor node selection schemes transmit the sensing
data from the sensor clusters via the relay to the sink. We derived the
expressions of outage probability and throughput for two sensor nodes. We
also provide numerical results to examine the behavior of the system. Finally,
we verify the validity of our analysis by using the monte-carlo simulation.

A low complexity distributed differential scheme based on orthogonal space t...IJECEIAES
This work proposes a new differential cooperative diversity scheme with high data rate and low decoding complexity using the decode-and-forward protocol. The proposed model does not require either differential encoding or channel state information at the source node, relay nodes, or destination node where the data sequence is directly transmitted and the differential detection method is applied at the relay nodes and the destination node. The proposed technique enjoys a low encoding and decoding complexity at the source node, the relay nodes, and the destination node. Furthermore, the performance of the proposed strategy is analyzed by computer simulations in quasi-static Rayleigh fading channel and using the decode-and-forward protocol. The simulation results show that the proposed differential technique outperforms the corresponding reference strategies.
Performance Analysis of OSTBC MIMO Using Precoder with ZF & MMSE EqualizerIJERA Editor
In this paper, a bit error rate analysis is presented for multiple-input–multiple-output (MIMO) system with finite-bit feedback is considered in PSK modulation technique, where a transmit signal consists of a rotational precoder followed by an orthogonal space–time block code (OSTBC) which achieve full diversity when a linear receiver, such as, zeroforcing (ZF) or minimum mean square (MMSE), is used. By choosing different parameters, codes with different symbol rates and orthogonally can be obtained .In this paper, we compare the performance of a family of space-time codes. Simulations show how the precoders obtained by our proposed criterion and method perform better bit error rate reduction compared to the existing ones.
Bit Error Rate Performance of MIMO Spatial Multiplexing with MPSK Modulation ...ijsrd.com
Wireless communication is one of the most effective areas of technology development of our time. Wireless communications today covers a very wide array of applications. In this, we study the performance of general MIMO system, the general V-BLAST architecture with MPSK Modulation in Rayleigh fading channels. Based on bit error rate, we show the performance of the 2x2 schemes with MPSK Modulation in noisy environment. We also show the bit error rate performance of 2x2, 3x3, 4x4 systems with BPSK modulation. We see that the bit error rate performance of 2x2 systems with QPSK modulation gives us the best performance among other schemes analysed here.

BER Analysis for Downlink MIMO-NOMA Systems over Rayleigh Fading ChannelsIJCNCJournal
The Multiple-input multiple-output (MIMO) technique combined with non-orthogonal multiple access (NOMA) has been considered to enhance total system performance. This paper studies the bit error rate of two-user power-domain NOMA systems using successive interference cancellation receivers, with zeroforcing equalization over quasi-static Rayleigh fading channels. Successive interference cancellation technique at NOMA receivers has been the popular research topic due to its simple implementation, despite its vulnerability to error propagation. Closed-form expressions are derived for downlink NOMA in single-input single-output and uncorrelated quasi-static MIMO Rayleigh fading channel. Analytical results are consolidated with Monte Carlo simulation.

Design and Implementation of a GPS based Personal Tracking SystemSudhanshu Janwadkar
Design and Implementation of a GPS based Personal Tracking System
Tracking based applications have been quite popular in recent times. Most of them have been limited to commercial applications such as vehicular tracking (e.g tracking of a train etc). However, not much work has been done towards design of a personal tracking system. Our Research work is an attempt to design such personal tracking system. In this paper, we have shared glimpses of our research work.
The objective of our research project is to design & develop a system which is capable of tracking and monitoring a person, object or any other asset of importance (called as target). The system uses GPS to determine the exact position of the target. The target is aided with a compact handheld device which consists of a GPS receiver and GSM modem. GPS receiver obtains location coordinates (viz. Latitude & Longitude) from GPS satellites. The location information in NMEA format is decoded, formatted and sent to control station, through a GSM modem. Due to use of Open CPU development platform, no external Microcontroller is required, with additional advantage of compact size product, reduced design & development time and reduced cost.
Thus, the proposed system is able to track the accurate location of target. This system finds applications in tracking old-age people, tracking animals in forest, tracking delivery of goods etc. Our final designed system is a small-size compact l.S"X3.7S" Tracker system with position accuracy error <30m (100 feet).
With advancement in CMOS technology, a lot of research has been done to develop various logic styles to improve the performance of logic circuits. D flip-flops (DFF) are fundamental building blocks in almost every sequential logic circuit. Hence, in sequential logic circuits, the overall performance of the circuit is affected by the performance of constituent DFFs. In recent years, the focus has been towards incorporating higher clock rates in a processor for better performance. To achieve high clock rates, fine granularity pipelining techniques are used, which implies that there are relatively a fewer levels of logic in each pipeline stage. A major consequence of this design trend is that the pipeline overhead has becoming more significant. The primary cause of pipeline overhead is the latency of the flip-flop or latch used to design the processor and the clock skew of the system. This calls out for the need of incorporating the logic functionality within the architecture of flip-flop. The new family of flip-flops are called Embedded Logic Flip Flops. In this Paper, we have reviewed various Flip-flop architectures which have been proposed so far. Our attempt is to do a qualitative analysis and comparison of the proposed Embedded logic flip-flop designs.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
