Abstract

Abstract:

The millimeter-wave array has many antenna elements and the beamforming algorithm in the frequency selective channel generally has a high complexity. In this paper, a low complexity iterative beamforming method in the frequency selective channel for the millimeter wave phased array is proposed. The method first obtains the beamforming vector which is adapted to the millimeter-wave phase array at one end of the communication, and then obtains the beamforming vector at the other end in the same way, and iterates in the communication transceiver side until the algorithm converges. Simulation results show that the beamforming vector obtained by this method can be of high channel capacity and achieves a higher transmission rate, and that it can converge after about three iterations, greatly reducing the overhead of link establishment.

Key words: millimeter wave , phased array, beamforming , multipath
