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.

Abstract: A downlink of multi-user non-orthogonal multiple access (NOMA) relay systems is considered. To improve system performance, relay nodes are used to forward signals from the base station (BS) to the end users, and they are… read more here.
