Abstract:
1. A method of path detection in a multi-path wireless communications system, comprising: receiving a wireless signal; configuring a plurality of sub-windows; selecting an objective for configuring a search window based on the plurality of sub-windows, wherein each of the sub-windows is smaller in size than the search window; providing a first counter for the objective; providing a separate second counter for each sub-window of the plurality of sub-windows; setting a threshold value as a reference for comparison; selecting a decision period for a duration of the objective; identifying whether at least one path is detected in each of the plurality of sub-windows; increasing the second counter for the each sub-window by one count if at least one path is detected in the each sub-window; repeating the steps of identifying and increasing until an end of the decision period; comparing counts of the second counters for the plurality of sub-windows with the threshold; and identifying a placement and a size of the search window.
