MATLAB Simulation for BPSK Demodulation

This MATLAB simulation program implements BPSK demodulation using baseband signals, incorporating several key functional modules. The matched filter module processes received signals through correlation-based filtering to maximize signal-to-noise ratio, typically implemented using convolution operations with the known pulse shape. The synchronization module employs timing recovery algorithms (such as early-late gate or Mueller-Muller methods) to maintain clock alignment between transmitter and receiver, ensuring proper sampling instants for symbol decision. The demodulation module converts the filtered and synchronized signals into digital bit streams using threshold detection and decision circuits, often involving coherent detection with carrier phase recovery. The BER calculation module compares the demodulated bit stream with the original transmitted data using error counting algorithms and statistical analysis to evaluate system performance. This simulation provides researchers and engineers with practical insights into BPSK demodulation principles, implementation techniques, and performance characteristics through executable code examples.
