Massive MIMO has the advantage of providing excellent multiplexing/diversity gain and data rate due to the large antenna array equipped at the BS or UEs. However, the high hardware cost and computational complexity limit the practical implementation of large antenna array. In this paper, we formulate a Minimum Mean Square Error (MMSE) based optimization model under the partially-connected structure...
Massive MIMO (Multiple-Input Multiple-Output) has the advantage of providing excellent multiplexing/diversity gain. However, the large antenna array will cause high hardware cost. Hybrid precoding is an effective method to reduce the RF (Radio Frequency) chains. In this paper, we formulate a MMSE-based (Minimum Mean Square Error-based) optimization model, propose a HP-MMSE (Hybrid Precoding-Minimum...
