1. Modulation in which an analog signal is converted to a digital signal by means of coding, such as in pulse-amplitude modulation (PAM), pulse-duration modulation (PDM), and pulse-position modulation (PPM). Common abbreviation PCM. 2. Modulation in which the pulse amplitude, pulse duration...
a pulse code modulation system, a five-unit code signal representing a given potential, e.g. a sample potential of a speech or other complex wave, is obtained by comparing the sample with a reference potential, the comparison being such that if the sample potential differs from the reference...

In order to improve the transmission rate and bit error rate (BER) performance of multi-carrier differential chaos shift keying system (MC-DCSK), a novel carrier phase and code index modulation differential chaos shift keying system (CP-CI-DCSK) is proposed in this paper. Reference and informat...
Block diagram of a point-to-point digital optical communication system with direct detection. The codes commonly considered in fiber-optics communications belong to the class of block codes. In an (n, k) block code the channel encoder accepts information in successive k-symbol blocks, adds n ...

A communication system by code modulation is described which incorporates an integration process in the original delta modulation system and is named delta-sigma modulation after its modulation mechanism. It has an advantage over delta modulation in dc level transmission and stability of performance, alt...
5012. [Class 40 (v)] In a pulse code modulation communication system, in which the signal amplitudes are represented by a pulse code of the binary type, a change of only one code element occurs when the signal amplitude changes by one step in any part of the amplitude scale. In a ...
