Quadrature amplitude modulation projects and source code

Implementation of 16 qam algorithm in the presence of awgn channel in matlab

The following Matlab project contains the source code and Matlab examples used for implementation of 16 qam algorithm in the presence of awgn channel . The program take an input stream of first 16 integers converted to binary form in the form of 4 bits least pass them on to the 4-bit register which takes first 2 bits to the I-channel and the next 2 bits to the Q-channel for modulation with cos and sin carriers respectively.

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
