Abstract

A method for operating a device includes determining adaptation criteria for a waveform to be transmitted by a transmitting device over a communications channel towards a receiving device, and adjusting a generalized multi-carrier multiplexing parameter (GMMP) of the waveform in accordance with the adaptation criteria.
