Compressed Training Based Massive MIMO

open access: yesIEEE Transactions on Signal Processing, 2019
Massive multiple-input-multiple-output (MIMO) scheme promises high spectral efficiency through the employment of large scale antenna arrays in base stations. In time division duplexed implementations, co-channel mobile terminals transmit training information such that base stations can estimate and exploit channel state information to spatially ...

On Out-of-Band Emissions of Quantized Precoding in Massive MU-MIMO-OFDM

open access: yes, 2017
We analyze out-of-band (OOB) emissions in the massive multi-user (MU) multiple-input multiple-output (MIMO) downlink. We focus on systems in which the base station (BS) is equipped with low-resolution digital-to-analog converters (DACs) and orthogonal ...
