Abstract

A method for communication over a communication link (20), which includes a transmitter (24) and a receiver (28), 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.
