Claim:
1. A method for detecting earliest arriving downlink signal peaks over all transmit diversity paths received at a same point in time, comprising: receiving, at a wireless mobile device, a wireless signal comprised of signals transmitted from a plurality of cells, each cell of the plurality of cells providing a plurality of transmit diversity paths; calculating, by the wireless mobile device, a channel energy response (CER) vector for each of the plurality of transmit diversity paths of each cell of the plurality of cells; constructing, by the wireless mobile device, an overlaid CER vector for each cell of the plurality of cells, wherein the overlaid CER vector for a cell comprises an overlay of each CER vector corresponding to each of the plurality of transmit diversity paths of the cell; and determining, by the wireless mobile device, an earliest arrival path (EAP) of each cell of the plurality of cells based on the overlaid CER vector for that cell.
