Optimal coordinated beamforming in the multicell downlink with transceiver impairments
Optimal coordinated beamforming in the multicell downlink with transceiver impairments
Physical wireless transceivers suffer from a variety of impairments that distort the transmitted and received signals. Their degrading impact is particularly evident in modern systems with multiuser transmission, high transmit power, and low-cost devices, but their existence is routinely ignored in the optimization literature for multicell transmission. This paper provides …
