A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, channel for AWGN (additive white Gaussian noise channel) channel (AWGN channel: do not consider communication channel signals, described by the scope of broadband wireless random statistical noise.). At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.
