Channel Tracking and Hybrid Precoding for Wideband Hybrid Millimeter Wave MIMO Systems
arXiv: Signal Processing, 2019.
A major source of difficulty when operating with large arrays at mmWave frequencies is to estimate the wideband channel, since the use of hybrid architectures acts as a compression stage for the received signal. Moreover, the channel has to be tracked and the antenna arrays regularly reconfigured to obtain appropriate beamforming gains ...More
