MATLAB Implementation of OFDM-MIMO System with SVD Decomposition

The OFDM-MIMO simulation program is designed to simulate a 2x2 MIMO system using Singular Value Decomposition (SVD) matrix factorization. This implementation utilizes MATLAB's built-in svd() function to decompose the channel matrix into singular vectors and values, enabling efficient signal precoding and decoding operations. The code structure includes modules for OFDM signal generation, channel modeling, SVD-based beamforming, and performance analysis metrics such as BER calculation. Through parameter adjustments in the simulation script, users can observe system performance variations by modifying parameters like SNR values, modulation schemes (QPSK, 16-QAM), and channel conditions. This simulation serves as an educational tool for understanding MIMO system principles, demonstrating practical implementation of SVD-based spatial multiplexing techniques in wireless communication systems. The program features commented code sections explaining key algorithms including channel matrix decomposition, power allocation across eigenmodes, and equalization processes for performance optimization.
