Abstract
A communication device includes a transmitter and a first idle detector. The transmitter is adapted to transmit digital data. The digital data includes user data. The transmitter includes a first idle symbol buffer for storing a first idle symbol. The first idle detector is adapted to detect an absence of user data. The transmitter is adapted to transmit the first idle symbol in response to detecting the absence of user data. A method for transmitting data includes defining a first idle symbol. The user data is stored in a buffer. The user data is modulated to generate a user symbol. An absence of user data in the buffer is detected, and the first idle symbol is transmitted in response to detecting the absence of user data.
