Abstract:This paper considers a multi-pair massive multipleinput multiple-output relaying channel where K single-antenna sources communicate with K single-antenna destinations via the assistance of a decode-and-forward relay equipped with massive antenna arrays. The relay station uses maximum-ratio processing to decode the signals transmitted from the sources and precode the signals before broadcasting to the destinations. To perform maximum-ratio processing, the relay needs to know the channels to the sources and the … Show more
