CORDIC-Based General Multiple Fading Generator for Wireless Channel Digital Twin

open access: yesSensors, 2023
A wireless channel digital twin is a useful tool to evaluate the performance of a communication system at the physical or link level by generating the physical channel controllably.

Improved Pilot-Aided Channel Estimation for MIMO-OFDM Fading Channels

open access: yesInternational Journal of Antennas and Propagation, 2013
An improved pilot-aided channel estimation scheme is proposed to enhance the channel estimation accuracy of multiple-input multiple-output-orthogonal frequency division multiplexing (MIMO-OFDM) fading channels. Based on the adaptive path number selection

On Channel Estimation for OFDM/TDM Using MMSE-FDE in a Fast Fading Channel

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
MMSE-FDE can improve the transmission performance of OFDM combined with time division multiplexing (OFDM/TDM), but knowledge of the channel state information and the noise variance is required to compute the MMSE weight.

Analysis of Coded FHSS Systems with Multiple Access Interference over Generalized Fading Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
We study the effect of interference on the performance of coded FHSS systems. This is achieved by modeling the physical channel in these systems as a block fading channel.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Binary Fading Interference Channel with No CSIT [PDF]

open access: yes2014 IEEE International Symposium on Information Theory, 2014
We study the capacity region of the two-user Binary Fading (or Erasure) Interference Channel where the transmitters have no knowledge of the channel state information. We develop new inner-bounds and outer-bounds for this problem. We identify three regimes based on the channel parameters: weak, moderate, and strong interference regimes.

Filter-Based Fading Channel Modeling

open access: yesModelling and Simulation in Engineering, 2012
A channel simulator is an essential component in the development and accurate performance evaluation of wireless systems. A key technique for producing statistically accurate fading variates is to shape the flat spectrum of Gaussian variates using ...

On the Analysis of Secrecy Outage Probability Using Average Channel Capacity

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020
In this article, we analyze the outage probability of physically secure wireless signal transmission in fading envi-ronments where both primary and eavesdropper channels are subject to generalized fading.
