Abstract

Aspects of a method and system for the extension of frequency offset estimation range based on correlation of complex sequences may include partitioning each of a received sample sequence and a local replica sample sequence into three or more similar length contiguous sample sub-sequences. For each of the three or more similar length contiguous sample sub-sequences, a correlation coefficient may be determined between corresponding sample sub-sequences of the partitioned received sample sequence and the local replica sample sequence. A plurality of phase differences may be determined based on adjacent ones of the determined correlation coefficients, and the determined plurality of phase differences may be averaged to generate a phase increment estimate. The communication system may be compliant with a wireless standard, comprising UMTS EUTRA (LTE), WiMAX (IEEE 802.16), and/or WLAN (IEEE 802.11).
