We consider wireless backhauling in mobile networks, employing large-scale full-dimension MIMO antenna arrays on both sides of the link. Our focus is on design strategies for transmit and receive antenna combiners, assuming FDD transmission and limited feedback operation. We investigate the performance of two competing philosophies: 1) An algebraic approach in which antenna combiners are calculated...
The employment of partial zero-forcing (PZF) receivers at the base stations represents an efficient and low-complexity technique for uplink interference management in cellular networks. In this paper, we focus on the performance analysis of ultra-dense networks (UDNs) in which the multi-antenna receivers adopt PZF. We provide both integral expressions and tight closed-form approximations for the probability...
