Ofdm transmission with rs code and comparision by digital modulation techniques in matlab

The following Matlab project contains the source code and Matlab examples used for ofdm transmission with rs code and comparision by digital modulation techniques. This is OFDM transmission,implemented without Reed Solomon Code.Also is compared on the basis of different digital modulations techniques such as (bpsk,Qpsk,m-ary psk...)

Ldpc Matlab Code

A low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel.  An LDPC is constructed using a sparse bipartite graph. LDPC codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close (or even arbitrarily close on the BEC) to the theoretical maximum (the Shannon limit) for a symmetric memoryless channel.

Qpsk performance comparison for wireline and wireless channel in matlab

The following Matlab project contains the source code and Matlab examples used for qpsk performance comparison for wireline and wireless channel. The symbols are transmitted using Quadrature Phase Shift Keying (QPSK) 4-QAM. Simulated BER is calculated using ML detection scheme. Theoretical expression is 2*p-p^2, where p is BER for BPSK modulation
