In this paper, we examine a signal separation method that restores the desired by multiplying power component and phase of reference signal, which is an unmodulated with same frequency as center signal. Gaussian-filtered minimum shift keying (GMSK) has not been evaluated in previous studies for synchronous detection feature demodulation method. The performance GMSK modulation was quantitatively...

In the new digital video broadcasting standard using satellites, denoted as DVB-S2, 16-ary and 32-ary amplitude-phase shift keying APSK are applied as modulation techniques. Optimum decision algorithms for 16-APSK and 32-APSK resulting from Voronoi diagrams demand relatively complicated hardware, typically high-capacity memories for demapping tables. In this paper, the efficient method based on...

The marriage of optical sensing techniques with sophisticated digital signal processing has resulted in a myriad of practical metrology systems. Optical metrology systems offer many attractive measurement features. These systems are inherently non-contacting, nondestructive, and immune from electromagnetic interference. In addition, since light is used as the sensing probe, the measurement syst...

Aim: To generate and demodulate an amplitude shift keyed (ASK) signal and a binary FSK signal. Amplitude shift keying-ASK-in the context of digital communications is a modulation process, which imparts to a sinusoid two or more discrete amplitude levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of which is ...

Amplitude demodulation is a classical operation used in signal processing. For long time, its effective applications practice have been limited to narrowband signals. In this work, we generalize amplitude wideband We pose as recovery problem of an oversampled corrupted and introduce special iterative schemes belonging the family alternating projection algorithms solve it. Sensibly chosen struct...
