Pulse modulation may be subdivided in to two types analog and digital. In analog the indication of sample amplitude is the nearest variable. In digital the information is a code. The pulse position ...

Pulse Position modulaion and demodulation simulation on proteus PPM is an analog modulating technique where the position of each pulse in relation to a reference pulse varies depending on the ...

The pulse position modulation (PPM) demodulation system for space laser communication based on the cascade of deep belief network (DBN) and support vector machine (SVM) is studied in this paper, and a ...

Pulse shaping enables successful demodulation at the receiver side. Orthogonal frequency division multiplex (OFDM) and orthogonal frequency division multiple access (OFDMA) are multiplexing and ...

The various methods for converting analogue signals into the form of pulse-code modulation and back again are reviewed. Reasons are given for preferring a particular method of conversion called ...
