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;

    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.
