Channel estimation for 60GHz wireless local area networks with massive receiving antennas

The utilization of the spectrum surrounding 60GHz can be a promising technology for wireless communication systems. This paper investigates the channel estimation problem for wireless systems at 60GHz frequency band with massive receiving antennas. The system model is built up over the massive frequency-selective channels. Moreover, an algorithm is proposed to estimate the large number of channel parameters. It is found that the suggested algorithm works well and can obtain all channel parameters without transmitting large number of training symbols. Finally, simulation results are provided to corroborate our proposed studies.
