Two-Transmit One-Receive STBC in Single-Path Rayleigh Channel

7. Two-Transmit One-Receive STBC in Single-Path Rayleigh Channel: (1) Analyze theoretical bit error rate performance and plot BER vs. Eb/N0 curves. (2) Design a specific pilot-assisted channel estimation method, implement Simulink simulation, and measure BER performance under BPSK modulation. Plot MSE of channel estimation vs. Eb/N0 curves and BER vs. Eb/N0 curves.
