Quadratically Constrained Myopic Adversarial Channels.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Information Theory. Aug2022, Vol. 68 Issue 8, p4901-4948. 48p.

Abstract: We study communication in the presence of a jamming adversary where quadratic power constraints are imposed on the transmitter and the jammer. The jamming signal is allowed to be a function of the codebook, and a noncausal but noisy observation of the ...

Channel Estimation for RIS-Aided Multiuser Millimeter-Wave Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Signal Processing. 2/15/2022, p1478-1492. 15p.

Abstract: Reconfigurable intelligent surface (RIS) is a promising device that can reconfigure the electromagnetic propagation environment through adjustment of the phase shifts of its reflecting elements. However, channel estimation in RIS-aided multiuser multip...

Massive MIMO Channels With Inter-User Angle Correlation: Open-Access Dataset, Analysis and Measurement-Based Validation.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Feb2022, Vol. 71 Issue 2, p1602-1616. 15p.

Abstract: In practical propagation environments, different massive MIMO users can have correlated angles in spatial paths. In this paper, we study the effect of angle correlation on inter-user channel correlation via a combination of measurement and analysis. We...

Secret Key-Enabled Authenticated-Capacity Region, Part—II: Typical-Authentication.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Information Theory. Nov2022, Vol. 68 Issue 11, p6981-7004. 24p.

Abstract: This paper investigates the secret key-authenticated-capacity region, where information-theoretic authentication is defined by the ability of the decoder to accept and decode messages originating from a valid encoder while rejecting messages from other...
