A Potent MIMO–OFDM System Designed for Optimum BER and its Performance Analysis in AWGN channel

Multiple-input Multiple-output (MIMO) systems use multiple antennas at the transmitter and receiver end, are a key technology to meet the growing demand for high data rate wireless systems. MIMO communication systems have the potential to provide increased capacity and reduced bit error rate and reliability without increasing the bandwidth or transmitted power. Obtaining this information, It’s paramount to design a knacky MIMO system to fulfill the growing demand for high data rate. In this purpose , Our research done and turned into complexion of the paper. The aim of this paper is to design MIMO-OFDM system with the aim of achieving the lowest and optimum Bit Error Rate (BER) while increasing the system capacity using multicarrier delay diversity modulation (MDDM), proposed for fifth generation systems. To implement the design Binary Phase Shift Keying (BPSK) chosen as constellation mapper and demapper rather than QAM and simulated using MATLAB, which is examined in associated Additive White Gaussian Noise (AWGN) channel models with no fading channel.
