Patent ID: 7593742

Claim:
A wireless transmit receive unit (WTRU) for use in wireless communications comprising: a post processing unit configured to process power delay profiles (PDPs) of received wireless signals where each PDP has a selected number of sequential elements that have values representing coherent accumulation of sequential sets of received samples mixed with a known sequence; the post processing unit configured to select less than half of the PDP elements of each PDP and to store the selected PDP elements' values and respective PDP position values; the post processing unit further configured to selectively combine stored PDP values such that the values of elements of each PDP of a set of corresponding PDPs that are stored for the same respective PDP position are combined; and the post processing unit further configured to evaluate the combined values for respective PDP positions against selected thresholds to pass threshold qualified combined values and respective position values for further signal processing for use in determining received signal paths of signals from which the respective PDP elements are produced.
