Full-dimensional (FD) massive multiple-input multiple-output (MIMO) has recently emerged as one of the physical layer enablers of 5G systems. Grounded on prior work on layered precoding. a novel framework for low-complexity multi-layer downlink precoding in multi-cluster cloud radio access network (C-RAN) systems using FD massive MIMO is introduced in this paper. The precoding matrix ... https://wholesfoodsboxs.shop/product-category/dairy/
