Abstract: Dynamic subarray achieves a compromise between the sum rate and hardware complexity of millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, in which antenna elements are dynamically partitioned to radio frequency (RF) chain according to… read more here.

Abstract: We propose a novel multi-user hybrid precoder design that imitates the bit error rate (BER) performance of a given fully digital precoder by minimizing the Frobenious norm between them. We show that the proposed design… read more here.

DOI: 10.1109/lcomm.2022.3140381
Abstract: We consider the downlink (DL) of a multi-user hybrid beamforming system having receiver IQ imbalance (Rx-IQI). For a generic channel model and any IQI unaware hybrid precoder, we derive a generalized expression of the DL… read more here.
