ABSTRACT:
A method and apparatus for reduced acquisition time are disclosed. In one embodiment, such as in a W-CDMA system, a receiver receives one or more signals from remote stations, each signal comprising a scrambling code associated with one of a plurality of code groups, each code group identified by a unique series of a synchronization codes. A searcher identifies a subset of first synchronization codes, and a processor selects one or more hypotheses in response to the received subset. The searcher may then perform searching for a scrambling code in accordance with the one or more hypotheses. The scrambling code search may be performed in parallel with continued synchronization code searching. Various other embodiments are also disclosed.
