WAVE PHASE MODULATION PROCESS Russian patent published in 2007 - IPC H03C3/38 

Abstract RU 2300837 C2

FIELD: radio engineering; providing high-quality communications over unstable communication channel.

SUBSTANCE: proposed process includes wave phase regulation in main and additional channels, variation of signal amplitudes using A and B factors, respectively, integration of output signals, and their normalization using factor. Main-channel signal is sine-waveform input signal, additional-channel signal is produced from input signal by integrating and differentiating it at a time; results of these operations are multiplied and square root is extracted from multiplication results.

EFFECT: eliminated dependence of regulated signal phase on input frequency.
