Patent ID: 7068592

Claim:
In data transmission systems, a method for increasing payload capacities comprising the steps of: determining a noise floor of a signal transmission system having a plurality of data bins; determining a type of data modulation in the signal transmission system; defining a desired bit-error rate (BER) associated with the signal transmission system; calculating a linear signal-to-noise ratio (SNR) of each individual data bin of the plurality of data bins, the SNR being a function of the determined noise floor, the determined type of data modulation, and the defined desired BER; comparing the calculated SNR of each individual data bin of the plurality of data bins to a predefined threshold SNR; defining individual data bins in the plurality of data bins as sufficient-capacity data bins having sufficient capacity for data transmission in response to the calculated SNR of the individual data bin being greater than the predefined threshold SNR; defining individual data bins in the plurality of data bins as insufficient-capacity data bins having insufficient-capacity for data transmission in response to the calculated SNR of the individual data bin being not greater than the predefined threshold SNR; loading the defined sufficient-capacity data bins with data for data transmission; clustering the defined insufficient-capacity data bins into bin-clusters having sufficient SNR for data transmission; and transmitting data using the bin-clusters and the sufficient-capacity data bins.
