Overview Pulse Code Modulation (PCM) is a method used to digitally represent analog signals. It involves sampling the analog signal at regular intervals, quantizing each sample into a digital value, ...

Phase-modulation and -demodulation techniques are more complex than modulation and demodulation based on amplitude and frequency. However, they provide the benefit of higher data rates for the amount ...

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 ...

Pulse compression is an important component of many modern radar systems. It is used to address the problem of a radar that needs simultaneously a long pulse width for detection at long ranges, and ...

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 ...
