Abstract
An integrated cell searcher of a dual mode modem, which supports different communication modes, is provided.
Claims19
An integrated cell searcher comprising:
- a first code generator which generates first codes for cell searching in a non-synchronous mode;
- a second code generator which generates second codes for cell searching in a synchronous mode;
- a signal selector which receives the first codes and the second codes, and selectively outputs either of the first codes or second codes, in response to a mode selection signal;
- and
- a plurality of correlators which receive and correlate a code from a base station and the selected codes, respectively.
