OFDM-MIMO Transceiver System

The OFDM-MIMO Transceiver System is a MATLAB-based communication programming simulator that implements key wireless communication technologies through structured code architecture. The system features a comprehensive GUI interface initiated by entering 'ui_start' in the MATLAB command window, which serves as the main entry point for the simulation environment. This framework enables researchers and engineers to study and simulate the performance characteristics of OFDM-MIMO communication systems through configurable parameter settings. The system incorporates multiple modular components including channel modeling algorithms (such as Rayleigh fading and AWGN channels), modulation schemes (QPSK, 16-QAM, 64-QAM implementations), coding rates, and antenna configuration parameters. Users can adjust these parameters through the GUI's interactive controls to simulate various communication scenarios and evaluate system performance metrics like bit error rate (BER) and channel capacity. Key functions include orthogonal frequency division processing through FFT/IFFT operations, spatial multiplexing algorithms for MIMO configurations, and channel estimation techniques. The simulator's code structure employs matrix operations for efficient signal processing and includes visualization tools for analyzing transmission results. This system demonstrates significant application potential in communication research, assisting researchers and engineers in understanding and optimizing OFDM-MIMO technology through practical simulation and algorithm verification.
