Monte Carlo simulation requirements for 4PSK communication system: (1) Plot four distinct phase modulation waveforms of 4PSK signals; (2) For an additive white Gaussian noise channel (mean=0, variance=1), display Monte Carlo simulation results of transmitting 1000 symbols under varying SNR conditions. The plot should use signal-to-noise ratio as x-axis and bit error rate as y-axis, comparing both actual BER (measured) and theoretical BER. Implementation requires programming with MATLAB or similar software tools, involving constellation mapping, noise generation, and BER calculation algorithms.

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.
