Abstract
In a multiband detector (DET), sub-band reconstruction and distortion compensation is performed by a plurality of digital filters (FIR , . . . , FIRk, . . . , FIRN) arranged in a single-input-multiple-output architecture. Each digital filter (FIRk) is coupled between one and the same input (RDA-I) whereto a distorted multiband signal (si) is applied and a respective output (RDA-Ok) whereto a reconstructed sub-band signal (sik) is applied. This multiband detector (DET) has a uniform architecture for each input-output path and can easily be adapted to changes in distortion of the multiband signal (si), even if these changes only affect a few sub-bands.
