Method and apparatus for determining frame timing
First Claim
1. A method of determining timing of synchronization portions of a target signal, the method comprising:
- receiving one or more signals, including the target signal, from one or more respective transmitters;
determining first observation time intervals that correspond to a first estimation of the timing of the synchronization portions of the target signal;
identifying first segments of the one or more signals that correspond to the first observation time intervals;
calculating first accumulated signal patterns, each accumulated signal pattern of the first accumulated signal patterns being calculated based on a respective subset of first segments within the identified first segments;
determining whether all of first accumulated synchronization words respectively derived from the first accumulated signal patterns match first corresponding ones of predetermined synchronization words; and
determining the first estimation of the timing of the synchronization portions of the target signal as the timing of the synchronization portions of the target signal in response to determining all of the first accumulated synchronization words match the first corresponding ones of the predetermined synchronization words.

Abstract
Aspects of the disclosure provide a method of determining frame timing of one or more signals from one or more respective transmitters. The method determining first observation windows that correspond to first candidate segments of the one or more signals; calculating a first set of accumulated signal patterns, each accumulated signal pattern of the first set of accumulated signal patterns being calculated based on signal patterns in a respective subset of the first candidate segments of the one or more signals; determining whether a first set of accumulated synchronization words derived from the first set of accumulated signal patterns is consistent with a first set of corresponding benchmark synchronization words; and determining the frame timing of the one or more signals based on timing of the first observation windows when the first set of accumulated synchronization words is consistent with the first set of corresponding benchmark synchronization words.
