MATLAB Implementation of MIMO-OFDM Simulation

The MIMO-OFDM simulation program is a comprehensive simulation tool featuring complete channel modeling and channel estimation implementations. This software enables researchers to conduct experiments with various channel simulations and estimation techniques, facilitating deeper understanding and investigation of MIMO-OFDM systems. The implementation typically includes modules for signal generation, spatial multiplexing/diversity encoding, OFDM modulation/demodulation, and realistic channel modeling with options for Rayleigh/Rician fading profiles. Users can simulate transmission performance under different channel conditions while adjusting and optimizing system parameters such as antenna configurations, modulation schemes, and pilot patterns. The channel estimation module employs algorithms like Least Squares (LS) or Minimum Mean Square Error (MMSE) estimators using preamble or pilot-based approaches for accurate channel state information recovery. The software provides an intuitive user interface with comprehensive documentation, allowing users to quickly become proficient and leverage its full capabilities. Key functions include configurable MIMO-OFDM transceiver chains, BER/SER performance analysis tools, and real-time visualization of constellation diagrams and channel frequency responses.
