Abstract
A multi-point communications system is set forth herein. The communications system includes a transmitter for transmitting OFDM/DMT symbols over a predetermined number of bins across a transmission medium. The OFDM/DMT symbols are generated using at least one timing signal. At least one of the predetermined number of bins includes a pilot tone sub-symbol having a frequency corresponding to a clock signal. The communications system may also include a receiver for receiving the OFDM/DMT symbols via the transmission medium. The receiver demodulates the received symbols using at least one timing signal.
