Device Activity Detection and Channel Estimation for Millimeter-Wave Massive MIMO
Device Activity Detection and Channel Estimation for Millimeter-Wave Massive MIMO
Millimeter-Wave Massive MIMO is important for beyond 5G or 6G wireless communication networks. The goal of this paper is to establish successful communication between the cellular base stations and devices, focusing on the problem of joint user activity detection and channel estimation. Different from traditional compressed sensing (CS) methods that …
