Abstract
A signal processor ( ) for recovering data symbols from a received signal includes matched filters ( ) for receiving and filtering a quadrature (Q) signal component of the received signal. A detector ( ) is coupled to the matched filters ( ) for selecting a filtered signal provided by one of the matched filters ( ) 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 ( ) then processes the Q channel output flag to generate a Q channel magnitude variable and a polarity variable, and a symbol decoder ( ) coupled to the Q channel symbol/sign decoder ( ) generates a data symbol in accordance with the Q channel magnitude variable and the polarity variable.
