Abstract
An apparatus and method for performing initial signal acquisition in a receiver of a millimeter wave wireless communication system. The apparatus comprises receiving a millimeter-wave signal including complementary sequences at the receiver; cross-correlating the received signal related to the received complementary sequences with respective predefined complementary sequences, wherein the received complementary sequences include a first type of complementary sequences and a second type of complementary sequences; performing a signal sequence detection by auto-correlating the cross-correlated first type of complementary sequences and comparing the auto-correlated results to an energy dependent threshold; and upon detection of the signal sequence, performing a timing synchronization to synchronize a start frame delimiter (SFD), wherein the timing synchronization includes in part a search for a peak in the cross-correlated first type of complementary sequences using a SFD search threshold.
