LEVERAGING SECONDARY SYNCHRONIZATION SIGNAL PROPERTIES TO IMPROVE SYNCHRONIZATION SIGNAL DETECTION

摘要

Disclosed is a method of synchronization signal correlation, comprising receiving a synchronization signal ("SS") on a plurality of receive antennas; performing a signal revision on the SS received on a first receive antenna, the signal revision comprising performing an element-wise squaring of the SS; calculating a complex coefficient by summing the element- wise squared SS; estimating a phase angle of the complex coefficient; and performing an element-wise phase correction of the SS; the method synchronization signal correlation further comprising performing the signal revision on the SS received on a second receive antenna; conditioning the revised signals by constructively and destructively combining the revised signals; selecting an optimized conditioned signal, wherein the optimized conditioned signal is the constructive or destructive combination with the largest Euclidian norm; correlating the optimized conditioned signal with a series of candidate SSs; and selecting the correlation with the largest magnitude as a transmitted SS.
