BER Analysis of MIMO OFDM System for AWGN & Rayleigh Fading Channel

Orthogonal Frequency-Division Multiplexing (OFDM) is essentially identical to coded OFDM (COFDM) and discrete multi-tone modulation (DMT). It is a frequency-division multiplexing (FDM) scheme, which is used as a digital multicarrier modulation method. The paper is aimed at analyzing the BER performance of the MIMO (Multi-Input MultiOutput) OFDM system for AWGN (Additive White Gaussian Noise) Channel, Rayleigh Fading Channel along with a simulation channel using different modulation technique. Also the result of the analysis suggest for the better technique in order to improve the BER characteristic of the MIMO-OFDM system. General Terms AWGN, OFDM, QAM, QPSK, Rayleigh Fading.
