TECHNIQUES FOR CHANNEL ESTIMATION IN MILLIMETER WAVE COMMUNICATION SYSTEMS
First Claim
1. 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 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, wherein 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.
