Joint Antenna Selection and Covariance Matrix Optimization for ISAC Systems
Michail Palaiologos, Mario H. Castãneda García, Tobias Laas +2
We consider an integrated sensing and communication (ISAC) system with a single communication user and multiple targets. For the communication functionality, the achievable rate is…
Optimal Beamforming for Bistatic MIMO Sensing
Tobias Laas, Ronald Boehnke, Wen Xu
This paper considers the beamforming optimization for sensing a point-like scatterer using a bistatic multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexi…
Limits of Transmit and Receive Array Gain in Massive MIMO
Tobias Laas, Josef A. Nossek, Wen Xu
In this paper, we consider the transmit and receive antenna array gain of massive MIMO systems. In particular, we look at their dependence on the number of antennas in the array, a…
On Reciprocity in Physically Consistent TDD Systems with Coupled Antennas
Tobias Laas, Josef A. Nossek, Samer Bazzi +1
We consider the reciprocity of the information-theoretic channel of Time Division Duplex (TDD) Multi-User-Multiple Input Multiple Output (MU-MIMO) systems in the up- and downlink.…
