Abstract
In this paper, a comprehensive BER performance simulative study has been made on data transmission in a downlink coordinated multipoint wireless communication System. The COMP MIMO OFDM system under investigation implements Turbo and LDPC channel coding, Spatially multiplexing and Space-time block coding (STBC), Doubly Spreading Minimum Mean Square Error (MMSE) and Zero Forcing (ZF) signal detection (Equalizers) schemes under 16PSK and 16QAM digital modulations based on the analysis it is remarkable that the simulated system is highly effective to combat inherent interferences under Rayleigh fading channel and provides robust performance in 16QAM, MMSE channel equalization and spatial multiplexing schemes.
