STTC (Space-Time Trellis Code) in Space-Time Coding with MATLAB Implementation

This text introduces STTC (Space-Time Trellis Code), a significant space-time coding method widely used in wireless communication systems. To facilitate better understanding and research of STTC encoding, we have developed MATLAB-based source code for system simulation. The implementation includes key components such as trellis structure initialization, state transition algorithms, and maximum likelihood sequence estimation (MLSE) using the Viterbi decoder. The source code enables comprehensive system simulation of STTC encoding, allowing performance evaluation through metrics like bit error rate (BER) analysis and signal-to-noise ratio (SNR) calculations. Using this code, researchers can simulate and analyze STTC performance across various communication scenarios, facilitating optimization and improvement based on specific requirements. The simulation framework incorporates channel modeling functions for Rayleigh fading environments and includes constellation mapping modules for different modulation schemes (e.g., QPSK, 16-QAM). This approach provides deeper insights into STTC applications, ultimately enhancing the performance and reliability of wireless communication systems through systematic coding analysis and practical implementation validation.
