MATLAB Simulation Program for BPSK Demodulation with Complete Receiver Chain

This MATLAB simulation program implements a complete BPSK demodulation system encompassing matched filtering, synchronization, demodulation, and BER calculation. The implementation begins with a matched filter designed to maximize the signal-to-noise ratio (SNR) by correlating the received signal with the known pulse shape. The synchronization module employs timing recovery algorithms (such as early-late gate or Mueller-Muller method) to align the sampling instants with the optimal decision points. For demodulation, the program implements coherent detection using carrier recovery techniques, typically involving phase-locked loops (PLL) or Costas loops for carrier phase estimation. The BER calculation module compares the demodulated bits with the original transmitted sequence, implementing error counting and statistical analysis to evaluate system performance. This simulation provides valuable insights into BPSK demodulation processes and performance characteristics through practical MATLAB implementation, including key functions like filter design, correlation-based timing recovery, and error rate computation algorithms.
