PROBLEM TO BE SOLVED: To provide a multi-band detector that suitably detects a multi-band signal of a different kind and is capable of flexibly adapting changes in distortion. SOLUTION: Sub-band reconfiguration and distortion compensation are conducted by plural digital filters (FIR1,..., FIRk,..., FIRN), configured to be a single input plural output architectures in a multi-band detector (DET). Each of the digital filter (FIRk) is coupled between one same input (RDA-I) to which a multi-band signal (si) is supplied and each of an output (RDA-Ok) to which a reconfigured sub band signal (sik) is supplied. The multi-band detector (DET) is easily adapted to these distortion changes, even when the distortion change in the multi-band signal (si) exerts an effect only on a sub band which is slightly changed. |
