Abstract: A method of maintaining a data rate of a telecommunications link that involves, in a particular embodiment, modulating a carrier signal, encoding the carrier signal, and dynamically controlling a bandwidth of the carrier signal by changing a symbol rate of the carrier signal such that a data rate of the carrier signal remains substantially equal to a predetermined data rate when the carrier signal is transmitted to a remote receiver.
