Abstract
In a method of identifying a time reference in signal received from a transmitter, a replica of a synchronization sequence is generated on the basis of at least one known transmission parameter and is compared to a sequence derived from the signal received from the transmitter to identify a reference point in the signal received from the transmitter.
Claims6
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.
