Implementation of MIMO-OFDM System Based on MATLAB (original) (raw)

MIMO-OFDM forms the basis of 3G/4G technology. Massive MIMO is considered as core technology in 5G. In this project, a multi-path Rayleigh fading channel environment is introduced. Then Multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) are individually implemented and their characteristics are studied. An environment to simulate a combined MIMO-OFDM system using space time block coding (STBC) is constructed using MATLAB. The results of 2x2 and 4x4 MIMO-OFDM system are compared and analysed with the system performance parameters such as signal to noise ratio and bit error rate.
