We demonstrate an experimental evaluation of unsupervised (i.e., blind) channel deconvolution that is based on the multi-user kurtosis (MUK) maximization criterion. We focus on the narrowband case and compare the performance of the MUK algorithm against the conventional trained 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.
