SEQUENTIAL QUADRANT DEMODULATION OF DIGITALLY MODULATED RADIO SIGNALS |
摘要 |
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 pi /n modulated signals.
