A novel phasedetection algorithm that does not need complete period sampling, phase-locked loops or complex electrocircuit hardware was presented in this paper.

The application of phase-locked and synchronous detection reduce the cost of the whole system and improve the sensitivity. Carrier signal and modulation signal achieve entirely synchronous too.
