Channel Feedback Based on AoD-Adaptive Subspace Codebook in FDD Massive MIMO Systems
Wenqian Shen, Linglong Dai, Byonghyo Shim +2
Channel feedback is essential in frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems. Unfortunately, previous work on multiuser MIMO has shown…

Codebook Design for Channel Feedback in Lens-Based Millimeter-Wave Massive MIMO Systems
Wenqian Shen, Linglong Dai, Yang Yang +2
The number of radio frequency (RF) chains can be reduced through beam selection in lens-based millimeter-wave (mmWave) massive MIMO systems, where the equivalent channel between RF…
