Abstract: Many applications used in communication systems involve bidirectional data transfer. In bidirectional data transfer applications, a client terminal has to turn on its hardware components such as transmitter at the time of transmitting the data and the receiver at the time of receiving the data.

This may reduce the rate at which the client terminal has to turn on and off its transmitter, receiver and other modules which may in turn reduce its power consumption.
