Abstract

The Geometric Mean Decomposition (GMD) based transceiver design has gained huge attention in the recent past as it provides an optimal solution in terms of BER and capacity. GMD technique has been widely adopted for the joint transceiver design as it converts the MIMO channel into identical and parallel SISO channels hence avoiding the necessity for bit loading and also achieves minimized bit error rates (BER). In this paper, we have explored the possibility of utilizing these positives of GMD for MIMO-OFDM transceiver designs, which is unavailable in the current literature. This paper considers the design of a linear Precoder and a DFE under perfect CSIT and CSIR. Using GMD, both MMSE and ZF based transceiver designs are proposed for MIMO-OFDM system. The performance of the proposed systems has been compared with other types of transceiver designs based on SVD and QR decomposition. The robustness of these proposed systems against the channel imperfections have also been analyzed.
