Abstract

[0072] A SPREAD SPECTRUM WIRELESS DEVICE (100) MAY INCLUDE A RECEIVER (110), A SEARCHER (128), A SEARCH CONTROLLER (130) AND OTHER FEATURES. THE SEARCH CONTROLLER (130) SELECTIVELY GENERATES CONTROL SIGNALS TO CONTROL THE SEARCHER (128) , WHICH SEARCHES FOR A SPREAD-SPECTRUM SIGNAL. IN ONE EMBODIMENT, THE ARCHITECTURE OF THE SEARCHER (128) IS DYNAMICALLY CONFIGURABLE BY THE SEARCH CONTROLLER (130) TO SELECTIVELY SEARCH MULTIPLE CHANNELS USING MULTIPLE FREQUENCY BINS FOR THE SIGNAL.(FIG 1)
