Abstract :
An over-the-air demonstration of unsupervised (blind) multiple-input/multiple output (MIMO) channel deconvolution is presented. The results were obtained in an indoor multiple antenna (BLAST) context. A suitable unsupervised MIMO technique was used in order to avoid the effective reduction of spectral efficiency caused by the use of channel training. To the authors´ knowledge, this may be the first reported experiment of successful over-the-air unsupervised MIMO deconvolution
