Soft-Output Finite Alphabet Equalization for mmWave Massive MIMO

Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi, Tom Goldstein, Christoph Studer

ICASSP 2020accepted

Nxt-generation wireless systems are expected to combine millimeter-wave (mmWave) and massive multi-user multiple-input multiple-output (MU-MIMO) technologies to deliver high data-rates. These technologies require the basestations (BSs) to process high-dimensional data at extreme rates, which results…

POKEMON: A non-linear beamforming algorithm for 1-bit massive MIMO

Oscar Castañeda, Tom Goldstein, Christoph Studer

ICASSP 2017accepted

One-bit quantization at the base-station (BS) of a massive multiple-input multiple-output (MIMO) wireless system enables significant power and cost savings. While the 1-bit uplink (users communicate to BS) has gained significant attention, the downlink (BS transmits to users) is far less studied. In…
