Abstract

The improved beamforming devices for communication systems operating in the mm-wave spectrum are particularly designed for antenna architectures consisting of antenna arrays, comprising multiple antenna array elements. The disclosed approaches comprise intelligent two stage searches, wherein information from the first stage is used in the second stage. This significantly reduces the computational complexity compared to the known approaches, with minimal loss in performance.
