More Information
Summary:A method and apparatus for decomposition of signals with varying envelope into offset components are disclosed here, that sample the time variant envelope of a single carrier (SC) or a multi-carrier (MC) band limited signal, quantizes the sampled value using Nb quantization bits and decomposes the sample into Nb in-phase and quadrature components that are combined in pairs and modulated to generate a set of Nb offset signals. The pulse shape applied in each offset signal is selected according to the spectral mask needed for the signal and to minimize envelope fluctuations in each offset signal from the set of Nb components.
