Experimental Evaluation of Unsupervised Channel Deconvolution for Wireless Multiple-Transmitter/Multiple-Receiver Systems
26 September 2002
In this paper we demonstrate experimental evaluation of unsupervised (i.e., blind) channel deconvolution that is based on the multi-user kurtosis maximization criterion. We focus on the narrowband case, and compare the performance of the algorithm against the conventional centralized linear MMSE and the V-BLAST algorithm. These results constitute, to the best of our knowledge, the first over-the-air demonstration of blind techniques for multiple-transmitter/multiple- receiver systems.
