Open the CIPO recordAbstract From the Canadian patent
Processing of information signals separated according to modulation and carrier components in a more controlled way is made possible by a device for processing an information signal (14) including means (20) for converting the information signal (14) to a time/spectral representation by block-wise transforming of the information signal and means (22) for converting the information signal from the time/spectral representation to a spectral/modulation spectral representation, wherein the means (22) for converting is designed such that the spectral /modulation spectral representation depends on both a magnitude component and a phase component of the time/spectral representation of …
