Simulation of a CDMA spread spectrum communication system using MATLAB functions. The system models synchronous communication for 6 users, each employing Gold codes of length L=31 for spreading, with transmission over an AWGN channel. The receiver uses matched filter detection for signal recovery. The simulation plots bit error rate (BER) curves for N=10000 transmitted bits across SNR values ranging from 0 to 15 dB, demonstrating system performance under varying noise conditions.
