1. A transmission system, comprising:
- a plurality of transmitters, each of the plurality of transmitters transmitting data in one of a plurality of transmission bands, at least one of the plurality of transmitters comprising a trellis encoder coupled to receive data to be transmitted;
a symbol mapper coupled to receive output signals from the trellis encoder;
at least one digital to analog converter coupled to receive output signals from the symbol mapper;
at least one filter coupled to receive analog output signals from the at least one digital to analog converter; and
an up-converter coupled to receive output signals from the at least one filter and shift a frequency of the output signal to an assigned frequency.

Abstract
A communication system is disclosed that allows high data-rate transmission of data between components. N-bit parallel data is transmitted in K-frequency separated channels on the transmission medium so as to fully take advantage of the overall bandwidth of the transmission medium. As a result, a very high data-rate transmission can be accomplished with low data-bit transmission on individual channels. A transmitter system and a receiver system are described for the communication system.

7. A transmission system, comprising:
a plurality of receivers, each of the plurality of receivers receiving signals from one of a plurality of transmission bands, at least one of the plurality of receivers comprising;
a down converter that converts an input signal from the one of the plurality of transmission bands to a base band;
a filter coupled to receive signals from the down converter, the filter substantially filtering out signals not in the base band;
an analog-to-digital converter coupled to receive signals from the filter and generate digitized signals;
an equalizer coupled to receive the digitized signals; and
a trellis decoder coupled to receive signals from the equalizer and generate recreated data, the recreated data being substantially the same data transmitted by a corresponding transmitter. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
