Doctoral student Felix Fellhauer will be attending this years IEEE International Workshop on Signal Processing Advances in Wireless Communications (SPAWC) in Sapporo, Japan.

There he will be presenting his paper: "Low Complexity Beamforming Training Method for mmWave Communications"

Abstract:

This paper introduces a low complexity method for antenna sector selection in mmWave Hybrid MIMO
communication systems like the IEEE 802.11ay amendment for Wireless LANs. The method is backwards
compatible to the methods already defined for the released mmWave standard IEEE 802.11ad. We
introduce an extension of the 802.11ad channel model to support common Hybrid MIMO configurations.
The proposed method is evaluated and compared to the theoretical limit of transmission rates found
by exhaustive search. In contrast to state-of-the-art solutions, the presented method requires
sparse channel information only. Numerical results show a significant complexity reduction in terms
of number of necessary trainings, while approaching maximum achievable rate.
