Channel Rtv Th Bangladesh

Dimensions extends the Tiles Document Assembly Framework of Struts 1.1/1.2 to become a multi-channel display framework capable of delivering customized content to virtually any device, any user role or other criteria in any format.

PircS is a PHP based IRC bot that logs channel statistics to an SQL backend and parses that data to generate text and graph representations of the channel traffic and events.

Implements soft-decision Viterbi decoding for a rate 3/4 code over an AWGN channel using Simulink.The Viterbi decoder block from the Communications Blockset is enhanced to optimally support punctured codes.The attached BERTool session file compares the BER performance as the number of bits are...

This is a simulator made in my thesis work (I've shown in my thesis work, that CDMA can increase channel capacity). It can simulate a CDMA encoding and decoding process.The data is assumed to be travelled through a coaxial cable. the effect of coax and CDMA is considered. You have to run the file...

The AWGN Channel Block in the Communications Blockset lets you specify SNR in several ways, including Eb/No. Sometimes people want to use a more itemized way of specifying the SNR, like the itemization found in a link budget.These two models show how to create equivalent implementations of a...

LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.


Platforms: Matlab

LU Decomposition is applied to a sparse banded matrix. We show how fill-ins can make solution by elimination not manageable. The same matrix is used to solve the Poiseuille flow problem in a rectangular channel using the finite differences approach. The result obtained using this numerical...
