Joint Detection in Multi-Antenna and Multi-User OFDM Systems

In this paper, a novel multi-antenna and multi-user system concept featuring combined application of joint detection and OFDM is introduced. To the well known advantages of OFDM as far as high bit rate communications are concerned, the elimination of multiple access interference offered by joint detection is added, rendering the proposed system highly suitable for beyond 3G communication systems. The air interface is described, and the transmission and detection models are derived. Moreover, some first results are presented, demonstrating the system performance in comparison to a reference detection case.
