Abstract
A method for automatic power and modulation management in a communication network includes (a) generating a discontinuous management function that is a weighted function of at least spectral efficiency and power consumption of the communication network, (b) determining, from the discontinuous management function, an optimal modulation format, an optimal forward error correction (FEC) rate, and an optimal output power of a transmitter of the communication network, which collectively achieve a maximum value of the management function, and (c) causing the transmitter to operate according to the optimal modulation format, the optimal FEC rate, and the optimal output power.
