  • Sequential quadrant demodulation of digitally modulated radio signals
    Publication number: 20010055348
    Abstract: This invention relates generally to a system and method for extracting data from a modulated signal, and more particularly to a system and method of demodulating constant-amplitude/continuous-phase digital radio modulated signals in a radio receiver. The data symbols are detected by establishing a complex trajectory of the modulated signal and interpreting the direction of the trajectory of the modulated signal as the digital data symbols. The invention has particular application to FSK-type modulated signals and more generally to &pgr;/n modulated signals.
