A practical MATLAB implementation example of DPSK signal modulation and demodulation using quadrature modulation techniques, featuring complete signal generation, processing, and performance analysis.
OFDM simulation program incorporating zero-forcing equalization, featuring complete modulation and demodulation processes, ideal for beginners
All sub-functions called by the main function can be freely modified for convenient usage. The available modules include: process control module, convolutional encoding/decoding module, interleaving/deinterleaving module, modulation/demodulation module, OFDM modulation/demodulation module, channel module (implementing multipath Rayleigh fading channel), and equalization module. These modules operate correctly and are well-suited for OFDM research. The code contains detailed annotations written by myself, making it easily understandable. A classic collection for signal processing research!
