LDPC pexit graph analysis

Protograph analysis of decoding threshold value, the traditional EXIT can not be used, so using the pexit diagram, is the most important tool for the analysis ofprotograph. This paper proposes a new external information transfer analys...

An Integrated Linear Programming Receiver for LDPC Coded MIMO-OFDM Signals

This work investigates the joint detection and decoding of MIMO-OFDM signals. Traditional receivers either utilize disjoint serial detector and decoder or require turbo message passing between the two functional blocks of detection and decoding. We present a novel approac...

spectrum approach, in a number of Acoustic Channel Drive and non-multi-path acou

Underwater spread spectrum system, the system uses direct sequence spread-spectrum approach, in a number of Acoustic Channel Drive and non-multi-path acoustic channel for the study of comparative...

DF,AF MATLAB simulation program

The program is using the Matlab simulation of cooperative communications DF (decode-and-forward) functions, and basic model S-R-D three nodes, the receiver using the MRC (maximal ratio combining). Fix DF because the SR channel error, its performance is limited, cannot be an effective diversity for S...
