Performance analysis of Multiband - OFDM systems using LDPC coder in pulsed -...IDES Editor
In this paper, a combined approach where low density
parity check (LDPC) codes are used to reduce the complexity
and power consumption of pulsed orthogonal frequencydivision
multiplexing (pulsed-OFDM) ultra-wideband (UWB)
systems is described. The proposed system uses LDPC codes
to achieve higher code rates without using convolution
encoding and puncturing thereby reducing the complexity and
power consumption of pulsed-OFDM system. The LDPCpulsed-
OFDM system achieves channel capacity with different
code rates and has good performance in different channel
fading scenarios. The pulsed OFDM system is used where
pulsed signals could spread the frequency spectrum of the
OFDM signal. The performance of LDPC-pulsed-OFDM
system for wireless personal area networks (WPAN) is
analyzed for different UWB indoor propagation channels (CM3
and CM4) provided by the IEEE 802.15.3a Standard activity
committee. To establish this, a design of LDPC-pulsed-OFDM
system using the digital video broadcasting-satellite-second
generation (DVB-S2) standard and provide the simulation
results for the different code rates supported by LDPC codes
is presented.

2) Newtec's networks provide the lowest total cost of ownership through features like converged all-IP technology, intra- and cross-layer optimization, and dynamic carrier management.
3) The networks are designed to evolve with emerging technologies such as DVB-S2 extensions, adaptive coding and modulation, and carrier identification to further improve efficiency and capacity.
The document discusses proposed extensions to the DVB-S2 satellite broadcasting standard to enable higher data rates for services like UHDTV. The extensions include reducing transponder roll-off factors and side lobes to fit more transponders in the same bandwidth, using wider 72 MHz transponders, adding a new 64-APSK modulation, and more modulation and coding options. These techniques could provide up to a 20% gain for direct broadcasting and up to 64% for professional links. The improvements will help deliver higher data rate ultra high definition and other bandwidth-intensive services over satellite.
This document discusses IPTV (Internet Protocol Television) and its key building blocks and protocols. IPTV allows distribution of TV content over IP networks and enables interactive viewing experiences. It uses H.264 video coding for high compression, supports multicast transmission, and requires a set-top box and broadband connection at the customer end. Key components include streaming servers, video servers, routers/switches, DSLAMs, and customer premises equipment. Quality of service is important for supporting real-time voice and video traffic.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
