Research on Equalization Techniques for MIMO-OFDM Systems

This research focuses on equalization techniques for MIMO-OFDM systems, including MATLAB implementation of signal fading algorithms in multipath channels. The study investigates the performance of MIMO-OFDM technology in multipath propagation environments and employs MATLAB to implement signal fading algorithms. We explore how equalization techniques can improve signal quality and system performance to achieve better communication results in multipath channel conditions. The research validates findings through experimental simulations and analytical methods, proposing potential improvements and recommendations. The MATLAB implementation involves key functions for channel modeling, equalizer design, and performance evaluation using algorithms such as MMSE (Minimum Mean Square Error) and ZF (Zero Forcing) equalizers to mitigate inter-symbol interference and channel distortion effects. Signal processing techniques include OFDM modulation/demodulation, MIMO spatial multiplexing, and channel estimation methods to handle frequency-selective fading characteristics typical in wireless communication scenarios.
