Limited Feedback Hybrid Precoding for Multi-User Millimeter Wave Systems
The large bandwidths in the mmWave spectrum make mmWave communication desirable for wireless local area networking and also a promising candidate for future cellular systems. Achieving high quality communication links in mmWave systems requires employing large antenna arrays at both the access point or base station (BS) and the mobile stations (MS). For efficient system performance, each BS needs to simultaneously serve a number of MS. Multiplexing different data streams to different users requires some form of precoding be applied to generate the transmitted signal at the BS.
