Patent ID: 8705661

Claim:
A method for performing channel estimation in a millimeter wave wireless communication system, comprising: receiving complementary sequences at a receiver of the millimeter wave wireless communication system, wherein the received complementary sequences are Golay complementary sequences generated at a first sampling rate; producing special complementary sequences from the received complementary sequences, wherein the special complementary sequences Golay complementary sequences; cross-correlating the special complementary sequences with an input signal related to the received complementary sequences, wherein the cross-correlation is performed at a second sampling rate and the second sampling rate is higher than the first sampling rate, wherein the cross-correlation is performed by a Golay correlator operating at the second sampling rate, wherein the Golay correlator includes log2(N) operation where N is a length of the received complementary sequences; 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.
