Abstract:
A method of equalizing performance of a composite channel made up of a plurality of parallel multiplexed transmission channels comprising:i) receiving a corresponding parallel plurality of forward error encoded signals from the composite channel; ii) determining a first plurality of Bit-Error-Rate (BERu) values for the corresponding parallel plurality of encoded signals received from the composite channel, wherein the first plurality of BERu values is determined prior to an application of forward error correction on any one of the corresponding parallel plurality of forward error encoded signals; iii) signalling for individual adjustment of each of a plurality of transmission powers over the plurality of parallel multiplexed transmission channels, respectively, based on the first plurality of BERu values, so as to equalize subsequent pluralities of BERU values; and iv) applying forward error correction decoding on each of the corresponding parallel plurality of forward error encoded signals received from the composite channel; and v) determining a second plurality of Bit-Error-Rate (BERc) values after the application of forward error correction decoding on each of the corresponding parallel plurality of forward error encoded signals; wherein the forward error correction provides an improvement between the first plurality of BERu values and the second plurality of BERc values in a known relation respectively.
