Abstract
Disclosed are techniques for detecting earliest arriving downlink signal peaks over all transmit diversity paths received at a same point in time. In an aspect, a wireless mobile device receives a wireless signal comprised of signals transmitted from a plurality of cells each providing a plurality of transmit diversity paths, calculates a channel energy response (CER) vector for each of the plurality of transmit diversity paths of each of the plurality of cells, constructs an overlaid CER vector for each of the plurality of cells, wherein the overlaid CER vector for a cell comprises an overlay of each CER vector of the plurality of transmit diversity paths of the cell, and determines an earliest arrival path of each of the plurality of cells based on the overlaid CER vector for that cell.
