Blind downlink channel estimation for TDD‐based multiuser massive MIMO in the presence of nonlinear HPA
In time division duplex (TDD)‐based multiuser massive multiple input multiple output (MIMO) systems, the uplink channel is estimated and the results are used in downlink for signal detection. Owing to noisy uplink channel estimation, the downlink channel should also be estimated for accurate signal...
