A coding scheme, used as a modulation technique, in which multiple channels are independently coded for transmission over a single wideband channel.
Note 1: In some communication systems, CDMA is used as an access method that permits carriers from different stations to use the same transmission equipment by using a wider bandwidth than the individual carriers. On reception, each carrier… (Read More →)

Synonym code-transparent data communication.

A mode of data communication that uses protocols that do not depend for their correct functioning on the data character set or data code used. Synonymcode-independent data communication.

1. Acronym for coder-decoder.
1. An assembly consisting of an encoder and a decoder in one piece of equipment.
2. A circuit that converts analog signals to digital code and vice versa.
