This collection includes simulation implementations for multipath channels, Doppler shift effects, Rayleigh and Rician channel models, along with QPSK modulation/demodulation and interleaving coding techniques. All programs have been thoroughly tested and verified as functional, accompanied by detailed test documentation and simulation graphical results demonstrating channel characteristics and signal processing performance.

When simulating with the rayleighchan function, it is essential to perform phase compensation at the final stage (a critical observation noted by the advisor). The procedural steps involve: generating random sequences, creating a Rayleigh fading channel, modulating the signal, retaining channel characteristics, transmitting the signal through the channel, applying phase compensation, adding Gaussian noise, demodulating the signal, calculating simulated bit error rate (BER), computing theoretical BER, and plotting BER curves in distinct colors for comparative analysis.

This work presents a relatively uncommon 16PSK simulation algorithm, including implementations for Gaussian channels, Rayleigh channels, and Linear Time-Invariant (LTI) channels. For the Rayleigh channel scenario, the algorithm provides comparative results before and after equalization, demonstrating the effectiveness of equalization techniques through performance metrics and visualizations.
