Abstract
A method for performing channel estimation in a millimeter wave wireless communication system. The method includes receiving complementary sequences at a receiver of the millimeter wave wireless communication system. The received complementary sequences are generated at a first sampling rate; producing special complementary sequences from the received complementary sequences; cross-correlating the special complementary sequences with an input signal related to the received complementary sequences. The cross-correlation is performed at a second sampling rate and the second sampling rate is higher than the first sampling rate; and analyzing the result of the cross-correlation to estimate at least characteristics of a channel between the receiver and a transmitter of the millimeter wave wireless communication system.
