Abstract:
1. A method of high-speed transmission, comprising: computing a signal quality of a received signal, the received signal being transmitted with a modulation order required by a default transmission modulation format; comparing the signal quality with a signal quality threshold required of the default transmission modulation format; if the signal quality is below the signal quality threshold, providing an indication of a level of signal quality failure to a transmitter; the transmitter setting a number of un-coded bits within the transmission signal based upon the level of signal quality failure, while maintaining a constant number of coded bits, allowing for changes in a transmission data rate while maintaining a constant transmission symbol rate; wherein the number of un-coded bits is 3 bits per two-dimensional modulation symbol if the signal quality is not less than the signal quality threshold, and is reduced by at least ½ bit per modulation symbol dimension if the signal quality is less than the signal quality threshold.
