To fully grasp the subject of coding for digital communications requires
a very good working knowledge of mathematics and it is difficult to give an introduction
to coding without either quickly losing the reader in complex equations and statistical
theory, or providing a superficial overview which lacks rigour. This chapter attempts to
inform the reader of the terminology and importance of coding for communications, but goes
no further. Good texts on the subject include, of course, Proakis (1989) and Halsall
(1992), from different perspectives. The term coding is applied to many operations within a communications system, including:
In many modern communication links, combinations of source, channel and modulation coding are employed in a dependent manner to optimize performance. |
