International Classification:

H04B 1/69

US Classification:

375147, 375148, 375152

Abstract:

A configurable cellular terminal engine (CTE) in accordance with an exemplary embodiment of this invention is configurable by an external agent (e. g. , microcontroller, DSP, or state machine) to suit the particular requirements of different spread spectrum systems. In an exemplary embodiment, the CTE comprises on a chipset a modem unit and a channel codec unit. The modem unit has a front end unit for coupling to an antenna; a matched filter searchers unit coupled at least to the front end unit; a searchers unit coupled to at least the front end unit; a finger processing unit coupled to the front end unit; a parameter estimation processor unit coupled to at least the finger processing unit and the searchers unit; and a transmitter unit. The channel codec unit has a channel decoder unit coupled at least to the finger processing unit; and a channel encoder coupled at least to the transmitter unit.

Abstract:

Briefly, according to the invention, a receiver (100) for receiving a carrier signal MSK (minimum shift keying) modulated with a bit stream of a digital information signal (302) is disclosed. The receiver (100) comprises a quadrature demodulator (128) for providing baseband quadrature demodulated signals (306 and 308). The quadrature demodulated (128) is coupled to an EXOR (126) for providing a decoded bit stream of the digital information signal (312) thereby avoiding complex decoder circuits. The quadrature demodulator (128) includes a pair of mixers (106 and 108) for quadrature mixing the received carrier signal and a pair of filters (114 and 118) for filtering the outputs of the mixers (106 and 108). The filters (114 and 118) are coupled to a pair of limiters (116 and 120) for limiting the filtered signals.
