Linear Computation Coding

Ralf R. Müller, Bernhard Gäde, Ali Bereyhi

ICASSP 2021accepted

We introduce the new concept of computation coding. For linear functions, we present an algorithm to reduce the computational cost of multiplying an arbitrary given matrix with an unknown vector. It decomposes the given matrix into the product of codebook and wiring matrices whose entries are either…

Outphasing Elements for Hybrid Analogue Digital Beamforming and Single-RF MIMO

Bernhard Gäde, Michael Amon, Ali Bereyhi, Georg Fischer, Ralf R. Müller

ICASSP 2019accepted

In conventional Multiple-Input Multiple Output (MIMO) systems, each antenna requires its own Radio Frequency (RF) chain. Since each RF-chain includes several active components that have to be synchronised, costs and complexity become restrictive. The outphasing MIMO and the outphasing precoder archi…
