On Space-Frequency Code Design with Partial Interference Cancellation Group Decoding

Abstract

Partial interference cancellation (PIC) group decoding proposed by Guo and Xia is an attractive decoding alternative for multiple-input multiple-output (MIMO) wireless communications. It can well deal with the tradeoff among rate, diversity and decoding complexity of space-time block codes. In this paper, two design criteria of full diversity space-frequency codes (SFC) are proposed for MIMO-OFDM systems with the PIC group decoding. Based on the criteria, a systematic design of full-diversity SFC with the PIC group decoding is proposed that can achieve full diversity and a rate of 2M t/(Mt + 1) for M t transmit antennas. Performance results demonstrate that the full diversity is offered by the newly proposed SFC with the PIC group decoding.978-1-4244-9268-8/11/$26.00 ©2011 IEEE This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE Globecom 2011 proceedings.
