Abstract:
Methods and systems for removing interference from strongly powered SSS sequences in a received signal so that comparatively weakly powered SSS sequences in the received signal can be detected are disclosed. The methods and systems can perform a first cell search using the received signal to detect a strongly powered SSS sequence. Using a known SSS sequence corresponding to the strongly powered SSS sequence, the channel over which the strongly powered SSS sequence is received can be estimated. The estimated channel can then be used to determine the contribution of the strongly powered SSS and PSS sequence to the received signal so that it can be canceled. With the contribution of the strongly powered SSS and PSS sequence canceled from the received signal, a second cell search can be performed using the received signal to detect a weakly powered SSS sequence.
