MATLAB Implementation of 802.11 Wireless Communication Protocol Simulation

802.11 Protocol Simulation with Complete Transmitter-Channel-Receiver Chain Implementation. The simulation processes transmit bit data (bit_source) through convolutional encoding, puncturing, rounding, interleaving, modulation, IFFT, and cyclic prefix addition. Channel effects are simulated via Rayleigh fading (bigfade), multipath propagation (multipath_chann), and AWGN addition (add_noise). The receiver performs CP removal, FFT, demodulation, deinterleaving, depuncturing, and Viterbi decoding to recover the original bit stream.
