A novel reduced-complexity near-optimal detection algorithm is proposed for enhancing the recent Coherently-detected Space-Time Shift Keying (CSTSK) scheme employing arbitrary constellations, such as ...

Just like it says on the tin, it’s phase shift keying, and a proper implementation uses a phase detection circuit or something similar.

Therefore, our proposal is to combine the iterative filter bank decomposition with the phase diagram analysis, a data-driven technique, applied in each frequency sub-band to address the detection of ...

This provides enough DC voltage to the input of the phase shift oscillator to start oscillation, and in turn the oscillator drives a piezo speaker.

An automatic method for classifying frequency shift keying (FSK), minimum shift keying (MSK), phase shift keying (PSK), quadrature amplitude modulation (QAM), and orthogonal frequency division ...

Common digital modulation techniques include amplitude-shift keying (ASK), frequency-shift keying (FSK), and phase-shift keying (PSK). ASK is the simplest of these techniques, and is used for low ...
