DoA Estimation with Compensation of Hardware Impairments

2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010
We consider the estimation of the direction of arrival (DoA) in the presence of hardware impairments that include the RF carrier frequency offsets, the phase offsets generated by an uncalibrated array, and the DC offset. The impairments model has been derived from the analysis of a hardware multiple antenna test-bed that uses direct down-conversion RF ...

Achievable Rate of Rician Large-Scale MIMO Channels With Transceiver Hardware Impairments

open access: yesIEEE Transactions on Vehicular Technology, 2016
Transceiver hardware impairments (e.g., phase noise, in-phase/quadrature-phase (I/Q) imbalance, amplifier non- linearities, and quantization errors) have obvious degradation effects on the performance of wireless communications.

On the Performance of LMS Communication With Hardware Impairments and Interference

IEEE Transactions on Communications, 2019
This paper investigates the performance of a dual-hop decode-and-forward (DF) relaying-aided land mobile satellite communication over Shadowed-Rician (SR) fading channels. A practical model for the satellite relaying system is first developed, where the impacts of satellite multi-beam antenna, radio propagation loss, and random shadowing are taken into

Outage Performance of Cooperative NOMA Networks with Hardware Impairments

2018 IEEE Global Communications Conference (GLOBECOM), 2018
We investigate the outage performance of cooperative non-orthogonal multiple access (NOMA) networks with transceiver hardware impairments, where the estimated channel state information and α-μ fading channels are considered. Closed-form expressions for the outage probability of cooperative NOMA networks are derived for two representative ...

Performance Analysis of RIS-SSK in the Presence of Hardware Impairments

2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021
Reconfigurable Intelligent Surface-based Space Shift Keying (RIS-SSK) was recently proposed as a promising transmission technique. In order to design strategic radio environments, this system takes advantage of RIS-based communication and adjusts the propagation channels.

Spatial Modulation for Terahertz Communication Systems With Hardware Impairments

IEEE Transactions on Vehicular Technology, 2020
Terahertz (THz) communication has emerged as a promising technology that efficiently alleviates the scarcity of the frequency resources, and is capable of providing Terabit-per-second (Tbps) data transmission. However, the hardware impairments, which are usually omitted in the low-rate systems, have a detrimental impact on the THz communication link ...

Channel Estimation for mmWave MIMO With Transmitter Hardware Impairments

IEEE Communications Letters, 2018
This letter considers the problem of channel estimation for millimeter wave (mmWave) multiple-input multiple-output systems under a transmitter impairments model. Specifically, taking the transmitter hardware impairments into account, the performance of conventional pilots-based channel estimation scheme will be degraded due to the destroyed training ...

Hardware Impairments-Aware Design of noncoherent Grassmannian Constellations

ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
In this paper, we propose a robust algorithm for designing unstructured Grassmannian constellations for noncoherent MIMO communications that accounts for the effect of hardware impairments (HWIs) such as I/Q imbalance (IQI) and carrier frequency offset (CFO).

Residual Transceiver Hardware Impairments on Cooperative NOMA Networks

IEEE Transactions on Wireless Communications, 2020
This paper investigates the impact of residual transceiver hardware impairments (RTHIs) on cooperative non-orthogonal multiple access (NOMA) networks, where generic $\alpha -\mu $ fading channel is considered. To be practical, imperfect channel state information (CSI) and imperfect successive interference cancellation (SIC) are taken into account.

Digital predistortion of hardware impairments for full-duplex transceivers

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
Digital predistortion is applied to account for all significant hardware impairments in a regeneration architecture full-duplex transceiver. Compared to a conventional regeneration architecture, where non-linearities are simply reconstructed for cancellation, by predistorting we avoid these components to achieve an improvement in both self-interference
