Abstract:
1. A method to automatically optimize channel throughput using current constellation size in a communication system having a set of current forward error parameters and a current data rate comprising: receiving input from one or more modules dedicated to identify and characterize impairments in the channel; analyzing the impairments to generate statistics on occurrences of impairments by virtually considering a plurality of forward error correction (FEC) parameters; searching for a set of new forward error correction parameters which provide maximal channel throughput; choosing a frame error target; estimating a new frame error rate and a new data rate for the set of new forward correction parameters based on the impairments statistics; and replacing the current forward error correction parameters with the new forward error correction parameters if the new data rate is greater than the current data rate and the new frame error rate is lower than the frame error target.
