Abstract
A method for communicating among nodes in a network includes determining, by a transmitter, a first frequency band and at least a second frequency band to be used for communicating data packets, wherein a maximum allowable power spectral density in the first frequency band is greater than a maximum allowable power spectral density in the second frequency band. The method also includes adjusting power spectral density for a first group of frequencies in the first frequency band such that the adjusted power spectral density of the first group does not exceed the maximum allowable power spectral density of the first frequency band and a quantization noise introduced by the transmitter is less than a threshold value for a signal transmitted in the second frequency band. The method further includes modulating at least a portion of a data packet transmitted by the transmitter to at least a first receiver in accordance with the adjusted power spectral density.
