On channel estimation and detection for multicarrier signals in fast and selective Rayleigh fading channels
TL;DR: Time-domain channel estimation and detection techniques are presented for multicarrier signals in a fast and frequency-selective Rayleigh fading channel and the theory of optimal low rank approximation is applied to a minimum mean squared error channel estimator and a theoretical calculation ofmean squared error is presented to confirm that the estimator is robust to changes in channel characteristics.
Journal ArticleDOI
Capacity of MIMO systems with antenna selection
TL;DR: An upper bound on the capacity that can be expressed as the sum of the logarithms of ordered chi-square-distributed variables is derived and evaluated analytically and compared to the results obtained by Monte Carlo simulations.
Journal ArticleDOI
Simultaneous Transmission and Reception: Algorithm, Design and System Level Performance
TL;DR: In this article, a closed-loop echo cancellation technique is proposed to cancel high-power echoes at the receive chain as echoes with powers much higher than the desired received signal, which can be implemented purely in the analogue domain.

TL;DR: The findings indicate that deploying the full-duplex principle can indeed also be feasible in mobile devices, and thus be one potential technology in, for example, 5G and beyond radio systems.
Journal ArticleDOI
Simultaneous Transmission and Reception: Algorithm, Design and System Level Performance
TL;DR: A closed-loop echo cancellation technique which can be implemented purely in analogue domain is presented and is robust to phase noise, does not require additional set of antennas, can be applied to wideband signals and the performance is irrelevant to radio frequency (RF) impairments in transmit chain.
