Abstract
A method and communication device adapted for interference cancellation in a cell search used in a communication device, including: correlating a signal received at the communication device with a template comprising one or more signal sequences associated with one or more corresponding cells to determine a metric for each of the signal sequences; and at least one iteration of: ranking the signal sequences based on the determined metrics, wherein the highest ranked signal sequence is designated as an aggressor sequence; performing an interference cancellation to generate a corrected metric for signal sequences based on their correlation with the aggressor sequence; and removing the aggressor sequence and setting priority to the cell associated with the aggressor sequence.
