BER Visualization for STBC System with MRC Receiver

In this paper, we investigate the Bit Error Rate (BER) visualization for Space-Time Block Coding (STBC) systems employing Maximum Ratio Combining (MRC) receivers. Given the complexity of STBC systems, we provide detailed explanations of fundamental principles including both encoding and decoding processes. The implementation typically involves matrix operations for STBC encoding and complex weight calculations for MRC combining. We further explore the operational principles of MRC receivers and demonstrate how to integrate them with STBC systems to maximize performance. The MRC algorithm optimally combines received signals by assigning weights proportional to the signal-to-noise ratio of each branch. Key functions would include channel estimation, signal combining, and maximum likelihood detection. Finally, we present BER visualization results through MATLAB simulations, showing performance curves across different SNR values. The code implementation would involve Monte Carlo simulations with parameterized modulation schemes, channel models, and antenna configurations. These results provide crucial insights for STBC system design optimization, particularly in determining optimal antenna configurations and power allocation strategies.
