1. In a code division multiple access wireless communication system, the system including an antenna, a base station multipath signal searcher for generating a plurality of search metrics from a plurality of multipath signals of a mobile station signal, and a base station transceiver for demodulating the mobile station signal, a method for detecting the mobile station signal comprising the steps of:

  • receiving the plurality of search metrics, each of the plurality of search metrics having an offset index and an offset energy value, the offset index corresponding to one of a plurality of time offsets associated with a multipath signal of the mobile station signal;

    calculating a plurality of decoding success predictors based on a plurality of combinations of the offset energy values, the plurality of decoding success predictors indicating a likelihood of successful mobile station signal demodulation;

    selecting a maximum decoding success predictor from the plurality of decoding success predictors; and

    acknowledging a mobile station signal detection by the base station transceiver if the maximum decoding success predictor has a value greater than zero.
