INFORMATION SIGNAL PROCESSING BY MODIFICATION IN THE SPECTRAL/MODULATION SPECTRAL RANGE REPRESENTATION |
摘要 |
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 including a unit for converting the information signal to a time/spectral representation by block-wise transforming of the information signal and a unit for converting the information signal from the time/spectral representation to a spectral/modulation spectral representation, wherein the unit 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 the information signal. A unit then performs a manipulation and/or modification of the information signal in the spectral/modulation spectral representation to obtain a modified spectral/modulation spectral representation. A further unit finally forms a processed information signal representing a processed version of the information signal based on the modified spectral/modulation spectral representation. |
