Claim:
1. A method for detecting a first and second secondary synchronization signal (SSS) sequence in a received signal, the method comprising: detecting the first SSS sequence in the received signal; estimating a channel over which the first SSS sequence is received as an element wise product of a frequency domain representation of samples of the received signal and a known SSS sequence corresponding to the first SSS sequence, wherein a value of the element wise product at a DC tone index is determined based on a value of the element wise product at a different tone index than the DC tone index; estimating a contribution of the first SSS sequence to the received signal using the channel estimate; canceling the contribution estimate of the first SSS sequence from the received signal to generate an interference canceled received signal; and detecting the second SSS sequence using the interference canceled received signal.
