Experimental result for a sdma mobile communications antenna array system

This paper presents experimental results for a Spatial Division Multiple Access cellular mobile communications system. The basestation antenna array testbed used to obtain the results is described in addition to sophisticated signal processing algorithms applied to the received data. These algorithms perform source tracking, beamforming for noise and interference reduction, and data detection. Simple experiments involving multiple co-channel users have been performed and results are presented in terms of output bit error rate. These results show that SDMA may be a technically feasible way to increase the spectrum efficiency of cellular mobile communications networks.Peer Reviewe
