Abstract:
1. A method of identifying a time reference in a signal received from a transmitter of a communications network, including: generating a replica of a synchronization sequence on the basis of at least one known transmission parameter; comparing the replica of the synchronization sequence to a sequence derived from the signal received from the transmitter of the communications network to identify a reference point, as the time reference, in the signal received from the transmitter of the communications network; wherein: the signal received includes one or more signals on a plurality of subcarriers and one or more transmission parameters including: a pilot channel symbol position; a scrambling code of the signal; and a subcarrier map of the signal; wherein generating the replication of the synchronization sequence comprises: generating a partial synchronization sequence replica for each subcarrier to be received; and combining the partial synchronization sequence replicate for each subcarrier into a single synchronization sequence replica.
