QPSK Modulation of Random Signals with Alamouti Space-Time Coding Scheme
This program performs bit error rate analysis across a range of SNR values. For each SNR level, it implements: random signal generation with QPSK modulation, Alamouti space-time block coding, transmission through Rayleigh fading channels with AWGN addition, maximum ratio combining at the receiver, and maximum likelihood detection to calculate symbol error rates. The implementation demonstrates that a symbol error rate of 10^-3 corresponds to approximately 12-13 dB SNR, validating the Alamouti scheme's performance in MIMO systems.
