Abstract
A system for receiving a transmitted signal is provided. The system includes a first receiver that can receive the transmitted signal and decode the transmitted signal according to a first demodulation format, such as a CDMA or PCS format. A second receiver, such as an FM demodulator, is connected to the first receiver at a suitable location, such as after initial signal amplification and processing has been completed. The second receiver can decode the transmitted signal according to a second demodulation format, such as AMPS.
Claims20
A system for receiving a transmitted signal comprising:
- an image reject mixer receiving the transmitted signal and generating a received signal;
- a first receiver coupled to the image reject mixer, converting the received signal to a phase-corrected received signal and decoding the phase-corrected received signal according to a first demodulation format;
- and
- a second receiver coupled to the image reject mixer, decoding the received signal according to a second demodulation format.
A system for receiving a transmitted signal comprising:
- a first receiver converting the transmitted signal to an in-phase received signal and a quadrature-phase received signal according to a first demodulation format;
- a phase shifter combining the in-phase received signal and the quadrature-phase received signal and shifting the combined signal;
- and
- a second receiver receiving the combined signal from the phase shifter and generating a second received signal according to a second demodulation format.
A method for receiving a transmitted signal comprising:
- image reject mixing the transmitted signal to generate a received signal;
- demodulating the received signal according to a first demodulation format;
- correcting a phase shift of the received signal;
- and
- demodulating the corrected received signal according to a second demodulation format.
