How Should IRSs Scale to Harden Multi-Antenna Channels?

Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3

This work extends the concept of channel hardening to multi-antenna systems that are aided by intelligent reflecting surfaces (IRSs). For fading links between a multi-antenna trans…

Secure Coding via Gaussian Random Fields

Ali Bereyhi, Bruno Loureiro, Florent Krzakala +2

Inverse probability problems whose generative models are given by strictly nonlinear Gaussian random fields show the all-or-nothing behavior: There exists a critical rate at which…

Channel Hardening of IRS-Aided Multi-Antenna Systems: How Should IRSs Scale?

Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3

Unlike active array antennas, intelligent reflecting surfaces (IRSs) are efficiently implemented at large dimensions. This allows for traceable realizations of large-scale IRS-aide…

Oversampled Adaptive Sensing via a Predefined Codebook

Ali Bereyhi, Saba Asaad, Ralf R. Müller

Oversampled adaptive sensing (OAS) is a Bayesian framework recently proposed for effective sensing of structured signals in a time-limited setting. In contrast to the conventional…

Linear Computation Coding

Ralf Müller, Bernhard Gäde, Ali Bereyhi

We introduce the new concept of computation coding. Similar to how rate-distortion theory is concerned with the lossy compression of data, computation coding deals with the lossy c…

Detection of Spatially Modulated Signals via RLS: Theoretical Bounds and Applications

Ali Bereyhi, Saba Asaad, Bernhard Gäde +2

This paper characterizes the performance of massive multiuser spatial modulation MIMO systems, when a regularized form of the least-squares method is used for detection. For a gene…
