BER Improvement in MIMO system using OFDM

Krishna N. Chaudhari, Dr. Dharmistha D. Vishwakarma, Anand B. Patel


Orthogonal frequency-division multiplexing (OFDM) is basically identical to the coded OFDM (COFDM) and discrete multi-frequency modulation (DMF).  OFDM is a scheme of FDM, which is used as a digital multi-carrier modulation method. This paper is aimed to analyzing the performance of the BER parameter of the Multiple Input Multiple Output-OFDM (MIMO-OFDM) system and MIMO for the AWGN (Additive white Gaussian noise) channel along with a simulation channel with the help of BPSK and M-QAM modulation techniques. Also analysed result suggests for the purpose of improving the characteristic of BER parameter of the MIMO-OFDM system.
