Modulation

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

Matlab code for qpsk modulation and demodulation in matlab

The following Matlab project contains the source code and Matlab examples used for matlab code for qpsk modulation and demodulation.  The QPSK modulation and demodulation technique which is simulated according to theory by matlab programming. The theoretical description of QPSK modulation and demodulation has described in book of "communication system " SIMON HAYKIN.

Ofdm Matlab Code

Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, whether wireless or over copper wires, used in applications such as digital television and audio broadcasting, DSL Internet access, wireless networks, powerline networks, and 4G mobile communications.
