Abstract

In this paper, we propose a systematic design of full-diversity space-frequency (SF) codes for multiuser MIMO-OFDM systems. With joint maximum likelihood detection, the proposed codes can obtain full diversity over selective-fading multiple access channels. The proposed coding scheme does not require the cooperation of multiple transmitters, nor the instantaneous channel side information at the transmitters but the channel statistics. Moreover, the proposed coding scheme is bandwidth efficient in that all users send their data streams through all OFDM subchannels simultaneously to make full use of the available bandwidth.
