Method and apparatus for recovering data symbols from a signal received by a radio communication device
A signal processor (125) for recovering data symbols from a received signal includes matched filters (210, 215) for receiving and filtering a quadrature (Q) signal component of the received signal. A detector (225) is coupled to the matched filters (210, 215) for selecting a filtered signal provided...

Summary: | A signal processor (125) for recovering data symbols from a received signal includes matched filters (210, 215) for receiving and filtering a quadrature (Q) signal component of the received signal. A detector (225) is coupled to the matched filters (210, 215) for selecting a filtered signal provided by one of the matched filters (210, 215) and for labeling the filtered signal according to a magnitude and phase of the filtered signal to provide a Q channel output flag. A Q channel symbol/sign decoder (235) then processes the Q channel output flag to generate a Q channel magnitude variable and a polarity variable, and a symbol decoder (240) coupled to the Q channel symbol/sign decoder (235) generates a data symbol in accordance with the Q channel magnitude variable and the polarity variable. |
