Foreign MIMO Simulation Program with BER Analysis

The foreign-developed MIMO program serves as a highly practical tool for measuring Bit Error Rate (BER) under different configurations of transmit/receive antenna counts and modulation schemes. By executing the ui-start command, users launch an interactive interface that allows customized parameter adjustments based on specific research or engineering requirements. The core algorithm implements spatial multiplexing techniques with configurable antenna arrays, supporting modulation schemes such as QPSK, 16-QAM, and 64-QAM through modular waveform generation functions. The program incorporates Monte Carlo simulation methods for statistical BER calculation, with built-in channel models simulating multipath propagation and noise effects. Key functionalities include real-time BER visualization through parametric sweep simulations, where users can observe performance trends across SNR ranges. The output generates detailed datasets and comparative graphs, enabling comprehensive analysis of system performance under varying antenna configurations and modulation orders. This facilitates accurate assessment and optimization of communication systems for reliable operation across diverse channel conditions. For implementation, the main simulation loop iterates through parameter combinations while the post-processing module generates performance metrics and visualization plots. The architecture supports extensibility for additional channel models and detection algorithms, making it valuable for both academic research and practical wireless system design.
