… channel estimation for massive MIMO systems1 with hybrid beamforming as shown in Fig. 1.
Here the massive MIMO … Cluster sparse channel model for mmWave massive MIMO systems…

… multiuser detection algorithm for massive MIMO systems equipped with a uniform planar
antenna array. We model the channel in the angular domain as a sparse matrix with the non-…

… To address the above issues, we propose a semi-blind detection scheme to jointly
estimate the channel and the user signals in a sparse massive MIMO system. We focus on the …

… for adaptive sparse recovery. Inspired by these two methods, we present an … sparse channel
estimation algorithm for massive MIMO systems. one can reconstruct the unknown K-Sparse …

… is simple and is suitable for most practical implementations, but it needs to carefully choose
training pilots and completely ignores the sparse property of the massive MIMO channels. …

… Many studies about massive MIMO are focused on the analysis of channel capacity, … the
uplink channel capacity in massive MIMO scenario and prove that all the three sparse cylindrical …

… In this work, we extend the sparse channel representation framework to joint uplink and …
downlink channel sparse representation to an uplink and downlink joint sparse representation. …

… In this article, we argue that exploiting the sparse properties of the channel in urban
environments and using the concept of coded CSI reporting can provide a solution. …
