Compressive sensing based differential channel feedback for massive MIMO
Massive multiple-input multiple-output (MIMO) is becoming a key technology for future 5G wireless communications. Channel feedback for massive MIMO is challenging due to the substantially increased dimension of MIMO channel matrix. In this letter, we propose a compressive sensing (CS) based differential channel feedback scheme to reduce the feedback overhead. Specifically, the temporal correlat...
متن کاملCell-Free Massive MIMO with Limited Backhaul
We consider a cell-free Massive multiple-input multiple-output (MIMO) system and investigate the system performance for the case when the quantized version of the estimated channel and the quantized received signal are available at the central processing unit (CPU), and the case when only the quantized version of the combined signal with maximum ratio combining (MRC) detector is available at th...
متن کاملWeighted Compressive Sensing Based Uplink Channel Estimation for TDD Massive MIMO Systems
In this paper, the channel estimation problem for the uplink massive multi-input multioutput (MIMO) system is considered. Motivated by the observations that the channels in massive MIMO systems may exhibit sparsity and the channel support changes slowly over time, we propose one efficient channel estimation method under the framework of compressive sensing. By exploiting the channel impulse res...
متن کاملUplink Interference Management in Massive MIMO Enabled Heterogeneous Cellular Networks
Considering the fact that massive multiple input multiple output (MIMO) macrocells and large number of small cells are deployed in the heterogeneous cellular networks for 5G, more users will be supported for uplink transmissions, which in turn brings more severe uplink interference. As a result, interference management is crucial for enhancing the uplink performance in these networks. In this l...
