A Principal-Component Approach to Antenna Impedance Estimation at MISO Receivers
IEEE COMMUNICATIONS LETTERS, 27(1), 288–292.
author keywords: Impedance; Maximum likelihood estimation; Receiving antennas; Training; MISO communication; Antennas; Transmitting antennas; Antenna impedance estimation; maximum-likelihood estimator; eigen-decomposition
TL;DR:
This letter study at MISO receivers over Rayleigh fading channels and derive the optimal ML estimator in closed-form, suggesting a computationally efficient, principal-components approach that estimates antenna impedance in real-time and shows sizable improvement against a reference estimator at low SNR.

Impedance Variation Detection at MISO Receivers
IEEE Communications Letters.
author keywords: Change detection; generalized likelihood-ratio test; maximum-likelihood estimator; MISO receiver
TL;DR:
The derived GLRT detector enjoys a better detection and false alarm trade-off when compared with a well-known, reference detector in simulations, and more transmit diversity significantly improves detection accuracy at a given false alarm rate, especially in slow fading channels.

2021 conference paper
A Hybrid Approach to Joint Estimation of MIMO Channel and Antenna Impedance Matrices
2021 55th Annual Conference on Information Sciences and Systems (CISS).
author keywords: Impedance Estimation; Channel Estimation; Maximum-Likelihood Estimator; Transmit Diversity
TL;DR:
This paper derives joint MAP/ML estimators for channel and impedance matrices in closed-form and develops a design principle leveraging a trade-off between channel and impediment estimation, which depends on transmit diversity.

A Hybrid Approach to Joint Estimation of Channel and Antenna impedance
2018 52nd Asilomar Conference on Signals, Systems, and Computers, 1789–1794.
TL;DR:
A hybrid approach to joint estimation of channel information and antenna impedance, for single-input, single-output channels, using joint maximum a posteriori and maximum-likelihood (MAP/ML) estimators for channel and impedance over multiple packets is considered.

Moments of Complex Gaussian Ratios
IEEE Communications Letters, 23(1), 88–91.
author keywords: Gaussian ratios; mean; absolute moments
TL;DR:
The mean of general CGR is calculated in a closed form and it is proved that the mean-square and higher order absolute moments are unbounded in general.

Training-Based Joint Channel and Antenna Impedance Estimation
2018 52ND ANNUAL CONFERENCE ON INFORMATION SCIENCES AND SYSTEMS (CISS).
author keywords: Channel Estimation; Impedance Estimation; Maximum-Likelihood Estimation; Training Sequences
TL;DR:
It is suggested that antenna impedance can be accurately estimated, in exchange for a small, controlled increase in channel estimation error, and maximum-likelihood estimators for the channel and impedance are derived.
