MATLAB Implementation of MIMO System with Space-Time Trellis Coding

This implementation models a MIMO communication system where the transmitter employs space-time trellis coding (STTC) for signal transmission. The wireless channel is characterized as Rayleigh fading, and the receiver operates with perfect channel state information (CSI). The MATLAB code provides a detailed framework that includes key components such as STTC encoder implementation using trellis structures, channel modeling with Rayleigh fading coefficients generation, and maximum likelihood sequence detection (MLSD) at the receiver using the Viterbi algorithm. The implementation allows researchers to analyze system performance through bit error rate (BER) calculations and spectral efficiency measurements. Additional features include modular code structure for easy modification of parameters like antenna configurations, modulation schemes (BPSK, QPSK), and frame sizes. The program serves as an excellent foundation for graduation projects, enabling further investigation of system performance under various conditions and exploration of alternative coding/modulation schemes to enhance overall system effectiveness.
