Emerging digital on-board processors for communication satellites concurrently ask for both tasks of the cascade of a frequency demultiplexer and a frequency multiplexer: i) mere de- and remultiplexing of an FDM signal (FDFMUX functionality) and ii) subband coding of one signal (SBC functionality). In this paper, the recently proposed oversampling FIR SBC-FDFMUX filter bank for two useful channels, which efficiently combines both tasks, is extended for higher channel numbers using Modified DFT filter banks. Moreover, a design example for the extended SBC-FDFMUX filter bank is given
