Abstract:
A communication device for communicating data through a data channel, the communication device comprising:a. a data transformer operably coupled with the data channel, the data transformer manipulating the data between data bits, a data bit vector, and a transmission symbol, the data bit vector having a selectable predetermined integer number of data bits selected from k or k+1 data bits, the transmission symbol containing a selectable integer number of the data bit vectors; and b. a controller operably coupled with the data transformer, the data transformer being responsive thereto, the controller adaptively selecting the selectable predetermined integer number of data bits, and the selectable integer number of data bit vectors to communicate the data through the data channel at a predetermined data bit rate in response to a data channel condition; wherein communication of the data through the data channel uses one or more signal constellations having a constellation size of either 2k or 2k+1.
