Patent ID: 7352704

Claim:
A method for multi-path searching in a mobile device such that the mobile device detects delays and gains of different propagation paths for a received signal, the method for the mobile device comprising: correlating data corresponding to a first one of the propagation paths of the received signal with a conjugate of a pilot channel sequence; repeating the correlation for other propagation paths of the received signal, wherein the other propagation paths correspond to a first set of propagation paths that also includes the first one of the propagation paths; coherently accumulating results corresponding to the correlation for the first set of propagation paths; calculating square-magnitudes of the coherently accumulated results corresponding to the first set of propagation paths; and comparing the calculated square-magnitudes of the coherently accumulated results corresponding to the first set of propagation paths to a threshold to identify first search results for the first set of propagation paths from the square-magnitudes of the first set of propagation paths that surpass the threshold, wherein the first search results include corresponding delays and gains for the first set of propagation paths.
