摘要：A demultiplexing apparatus includes, in each of n stages, 2FC+RXHBFs that

down-sample a signal, from which a high-frequency component is removed after

frequency conversion is carried out, and output the signal. The demultiplexing apparatusextracts, from an input signal including a plurality of band signals, the band signals tothereby demultiplex the input signal. The demultiplexing apparatus includes a reception-filter-bank control unit that calculates, based on channel information including bands andfrequency arrangement of the band signals, a dividing position on a frequency axis and afrequency offset value indicating a frequency conversion value and instructs the

FC+RXHBF, which is set as a target of output of divided signals of the input signal, aboutthe calculated values. The FC+RXHBF carries out frequency conversion based on thefrequency offset value.
