Blind Signal Detection in Massive MIMO: Exploiting the Channel Sparsity.
IEEE Transactions on Communications(2018)
摘要
In practical massive MIMO systems, a substantial portion of system resources are consumed to acquire channel state information (CSI), leading to a drastically lower system capacity compared with the ideal case, where perfect CSI is available. In this paper, we show that the overhead for CSI acquisition can be largely compensated by the potential gain due to the sparsity of the massive MIMO channel...
