Cooperative communication is a novel class of wireless communication

In this paper, a comprehensive study has been made on performance assessment of a single relayed cooperative wireless communication system under implementation of OFDM aided MIMO technology. This paper provides a new insight on system performance with proposed STBC encoded MIMO-OFDM radio interface technology, four channel equalization techniques (ZF, MMSE, ZF-SIC and MMSE-SIC) and three digital modulation schemes (BPSK, QPSK and QAM). Simulation results show that the STBC encoded single relayed MIMO-OFDM cooperative wireless communication system with BPSK and MMSE-SIC outperforms as compared to other digital modulations and channel equalization schemes on scrambled voice frequency signal transmission.
