This paper presents an iterative algorithm for differential block demodulation of amplitude-phase-shift keying in channels whose characteristics change within a block. The algorithm has some features ...

Differential-Self-Multiplication (DSM): An algorithmic technique designed to reduce errors arising from phase modulation depth variations, thereby enhancing sensor accuracy.

A versatile four-quadrant analog multiplier core from Analog Devices, the AD633, is widely used in applications like modulation and demodulation, automatic gain control, power measurement, and ...
