Design options of the versatile oversampling two-channel SBC-FDFMUX filter bank

Modern FDM communication systems demand highly efficient digital processors, which flexibly allow for allocating different bandwidths to different users (Maufroid et al., 2003). Hence, for the processing of the incoming signal, two processor tasks must be distinguished: i) Mere demultiplexing of an FDM-signal and ii) demultiplexing of a single wideband signal with subsequent perfect reconstruction. This paper investigates and compares design options of the novel SBC-FDFMUX filter bank that efficiently combines both of the above tasks.
