Abstract
In telecommunication, there are various ways to communicate between two points, referred to as mode of operation. This is usually done in three ways: simplex, half-duplex, and full duplex. Simplex is a one-way communication such as broadcasting. Half duplex is a two-way communication but one at a time such as taxi dispatch system. Full duplex is a method of two-way communication, where two users can communicate with each other simultaneously such as land-mobile telephone system. In full duplex communication, the link is maintained in both directions, either in the frequency domain or in the time domain. This is governed by two basic communication schemes: frequency division duplex (FDD) and time division duplex (TDD). A brief description of these communication modes is presented in this chapter.
