Wireless transceivers for mass-market applications must be cost effective. We may achieve
this goal by deploying non-ideal low-cost radio frequency (RF) analog components …

The performance of full-duplex (FD) cooperative non-orthogonal multiple access (C-NOMA)
relaying systems in the presence of in-phase and quadrature-phase imbalance (IQI) and …

In this article, an algorithm for joint estimation of communication channel gains and signal
distortions in a direct conversion receiver is proposed. The received signal model uses …

In this paper, we consider the uplink (UL) communication of a massive multi-user (MU)
multiple-input multiple-output (MIMO) hybrid beamforming system (HBFS) in which the …

The impairments due to in-phase and quadrature-phase imbalance at the transmitter and/or
receiver, carrier frequency offset, and doubly selective channel (DSC) result in multiuser …

Data transfer in a wireless channel environment is plagued by numerous security issues and
power transmission loss. Channel state information is crucial to attaining the performance …

The article is devoted to the algorithm for joint estimation of the non-stationary channel and
signal distortions in the direct conversion receiver, based on the use of polynomial …

In this paper, we consider the impact of IQ imbalance (IQI) on the achievable information rate
of low complexity linear multi-user receivers in IQ-impaired uplink massive multiple-input …

The article discusses the algorithm for the joint estimation of the stationary channel factors
and signal distortions, such as DC drift, the frequency shift remaining from the demodulation …

Although the mean square error (MMSE) approach is recognized to be near optimal for
uplinking large-scale multiple-input-multiple-output (MIMO) systems, there are certain …
