Abstract
A method for communication over a communication link, which includes a transmitter and a receiver, includes transmitting and receiving data, which is encoded using a specified forward error correction (FEC) code, modulated using a specified modulation scheme and transmitted at a given power level.One or more parameters of the communication link are monitored. A condition, which is based on values of one or more of the parameters monitored at a plurality of historical time instants, is evaluated. At least one feature of the transmitted data, selected from a group of features consisting of the FEC code, the modulation scheme and the power level, is modified based on the condition.
