Is Lattice Reduction Necessary for Vector Perturbation Precoding?
Dominik Semmler, Wolfgang Utschick, Michael Joham
Vector perturbation (VP) precoding is an effective nonlinear precoding technique in the downlink (DL) with modulo channels, providing an approximation of dirty paper coding (DPC) w…
Performance Analysis of Systems with Coupled and Decoupled RISs
Dominik Semmler, Josef A. Nossek, Michael Joham +1
We analyze and compare different methods for handling the mutual coupling in RIS-aided communication systems. A new mutual coupling aware algorithm is derived where the reactance o…
A Zero-Forcing Approach for the RIS-Aided MIMO Broadcast Channel
Dominik Semmler, Michael Joham, Wolfgang Utschick
We present efficient algorithms for the sum-spectral efficiency (SE) maximization of the multi-user reconfigurable intelligent surface (RIS)-aided multiple-input multiple-output (M…
High SNR Analysis of RIS-Aided MIMO Broadcast Channels
Dominik Semmler, Michael Joham, Wolfgang Utschick
We analyze the influence of a reconfigurable intelligent surface (RIS) on the Gram channel eigenvalues in a high signal-to-noise ratio (SNR) scenario. This allows to connect specif…
