High-Bandwidth Spatial Equalization for mmWave Massive MU-MIMO with Processing-In-Memory
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
All-digital basestation (BS) architectures enable superior spectral efficiency compared to hybrid solutions in massive multi-user MIMO systems. However, supporting large bandwidths…
Improving Channel Charting with Representation-Constrained Autoencoders
Pengzhi Huang, Oscar Castañeda, Emre Gönültaş +4
Channel charting (CC) has been proposed recently to enable logical positioning of user equipments (UEs) in the neighborhood of a multi-antenna base-station solely from channel-stat…
VLSI Design of a 3-bit Constant-Modulus Precoder for Massive MU-MIMO
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
Fifth-generation (5G) cellular systems will build on massive multi-user (MU) multiple-input multiple-output (MIMO) technology to attain high spectral efficiency. However, having hu…
