Abstract

Abstract

In this paper a design criteria of full diversity space frequency codes (SFC) is proposed for MIMO-OFDM systems with a low complexity detection scheme. It can achieve full diversity. This system utilizes space distributive properties of SFCs to make correct decisions. In the proposed scheme detection of SFCs is done using a novel minimum Euclidean distance metric calculation method followed by decision making. It can achieve the performance of partial interference cancellation methods. Partial interference cancellation (PIC) group decoding is an attractive decoding alternative for MIMO wireless communications. It can well deal with the tradeoff among rate, diversity and decoding complexity of SFC codes. Simulation results of the newly proposed codes demonstrate the theory.

Index Terms:  MIMO-OFDM, SFC, ML decoding, PIC group decoding.
