Abstract

Adjusting parameters of a waveform includes facilitating wireless communication between a transmitting node and receiving nodes, where the transmitting node communicates with a receiving node over a channel. Spectrum conditions are estimated, where a spectrum condition describes spectrum utilization in the vicinity of ρsurrounding nodes. Channel conditions are estimated, where a channel condition describes a channel of the plurality of channels. Waveform parameters are adjusted in response to the spectrum conditions and the channel conditions.
