Main function Alamouti(Nr, max_snr, max_err_symbol, symbol_per_frame) implements the Alamouti space-time coding scheme with the following components: QpskMapping(psudo_bit_sequence) - converts binary data to QPSK modulated symbols; RayleighCH(Nr, Nt) - simulates Rayleigh fading channel characteristics. Example usage: Alamouti(1, 12, 20, 24). Key parameters: 2 transmit antennas and 1 receive antenna configuration, SNR range from 0dB to 12dB, simulation stops when symbol errors exceed 20 at each SNR point, with 24 QPSK symbols per frame.

Simulation of the channel impulse response for a Rayleigh fading channel, where the x-axis represents the channel sampling order and the y-axis represents the amplitude value corresponding to each sampling order. This implementation typically involves generating complex Gaussian random variables to model the fading coefficients and computing the magnitude for visualization.
