Abstract
A method for use in a wireless communication system comprising a transmitter and a receiver, the method comprising receiving, in the receiver, data comprising a plurality of channel-distorted synchronization codes and plurality of channel-distorted cipher codes, generating a receiver cipher sequence at the receiver, the receiver cipher sequence comprising a plurality of receiver cipher codes, analysing the received data to identify correlations between the plurality of channel-distorted cipher codes in the received data and the plurality of receiver cipher codes, accumulating the identified correlations as accumulator data in an accumulator, identifying one or more peaks in the accumulator data, identifying a first correlation peak in the accumulator data that meets one or more criteria and using the first correlation peak to identify the first path of a data packet from the transmitter.
