MPSK (BPSK, QPSK, 8PSK) Simulation with Theoretical and Experimental Results Using Gray Coding

This MATLAB m-file implements a comprehensive MPSK (BPSK, QPSK, 8PSK) simulation with Gray coding, comparing theoretical and experimental bit error rate (BER) performance. The code includes practical satellite link design examples using QPSK and 8PSK modulation schemes under band-limited conditions where bit rate (Rb) exceeds channel bandwidth (Wc). The simulation employs constellation mapping with Gray coding to minimize bit errors and implements Monte Carlo methods for BER calculation.
