Abstract:
1. A process of changing a waveform type of modulated waveforms generated and transmitted by a sending node to a receiving node, wherein said waveform type is defined by a parameter set that sets modulation characteristics of said waveform type, said process comprising: receiving at said sending node digital communications to be transmitted to said receiving node; processing said digital communications hierarchically at each layer of a stack of hierarchical processing layers within said sending node, said processing producing at a second lowest processing layer in said stack bit streams corresponding to said digital communications; modulating in a lowest processing layer in said stack in said sending node said bit streams into waveforms of a current waveform type to produce bit-stream-modulated waveforms of said current waveform type; transmitting said bit-stream-modulated waveforms from said sending node through a transmission medium to said receiving node; and upon determining to change said current waveform type to a new waveform type:
