ABSTRACT:
The present invention provides for receiving a radio frequency signal which encodes transmitted data, and for outputting data corresponding to the transmitted data. The radio frequency signal is received and converted to inphase and quadrature data. Phase information is extracted from the inphase and quadrature data. A symbol timing for the radio signal is determined based on the extracted phase information. The transmitted data encoded within the radio frequency signal is detected and processed based on the determined symbol timing. Data is output based on the detected and processed transmitted data. Since symbol timing is determined based on phase information, in the phase domain, a radio frequency receiver can be constructed with a lower complexity and a simpler structure.
