Abstract
A demultiplexing apparatus includes: a demultiplexed-signal selecting and distributing unit configured to apply frequency conversion processing and down-sampling processing to one or more reception signals and output reception signals to a designated output destination; frequency converting and reception low-pass filter units configured to apply frequency conversion processing and low-pass filter processing to reception signals and output reception signals while down-sampling reception signals; selector units configured to switch an input source of a signal output to the frequency converting and reception low-pass filter unit at a next stage; reception-channel filter units configured to subject signals from the frequency converting and reception low-pass filter units to waveform shaping with a desired frequency characteristic and output the signals; and a filter-bank control unit configured to generate, based on channel information estimated from one or more reception signals, a control signal controlling the demultiplexed-signal selecting and distributing unit and the selector units.
