Abstract

Through the use of a variable state length initialization, both the transmitter and the receiver of a multi carrier communication system can have control of the length of one or more initialization states. A transmitter sends information, such as a message, to the receiver at the commencement of, during initialization or prior to entering a variable length initialization state. The information can specify , for example, a minimum length of an initialization state as needed by the transmitter.
