802.11g wlan phy model in matlab

The following Matlab project contains the source code and Matlab examples used for 802.11g wlan phy model. Modulator has been initialized as % number of bits per symbol switch modulation                 case 'BPSK', Nb1 = 1;                 case 'QPSK', Nb1 = 2;                 case '16-QAM', Nb1 = 4;                 case '64-QAM', Nb1 = 6;     case 'DQPSK', Nb1 = 8;     case 'OQPSK', Nb1 = 16; end modOrder = 2.

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.

A bfsk de modulator. in matlab

The following Matlab project contains the source code and Matlab examples used for a bfsk de modulator.. A BPSK Demodulator Function, where x is the BPSK Input, fc is the carrier frequency, and T is the symbol (bit) duration, nbits is the number of bits, and b is the Output bit stream. Syntax:: [b]=bfsk_demod(x,fc,T);

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.
