System and method for increasing payload capacity by clustering unloaded bins in a data transmission system

In data transmission systems, a method for increasing payload capacities comprising the steps of:

• modulating data bins to produce bin-clusters, wherein a signal-to-noise ratio (SNR) of each individual data bin of a plurality of data bins is computed, the data bins are selectively clustered into bin-clusters having sufficient SNR for data transmission, wherein the computed SNR of each individual data bin of a plurality of data bins is compared with a predefined threshold SNR, and the individual data bins having a computed SNR not greater than the predefined threshold SNR are sequentially added to a bin-cluster until the linear sum of the SNR of each sequentially added individual data bin exceeds the predefined threshold SNR;
• loading the bin-clusters with data;
• transmitting the loaded bin-clusters;
• receiving the transmitted bin-clusters;
• and
• extracting data from the received bin-clusters.
