Document Type and Number:
Japanese Patent JP5579273
Kind Code:
B2
Abstract:
It is an object of the present invention to obtain a demultiplexing apparatus in which a circuit size can be reduced. The demultiplexing apparatus includes a demultiplexed-signal selecting and distributing unit 130 configured to apply frequency conversion processing and down-sampling processing to one or more reception signals and output the reception signals to a designated output destination, frequency converting and reception low-pass filter units 101 to 114 configured to apply frequency conversion processing and low-pass filter processing to the reception signals and output the reception signals while down-sampling the reception signals, selector units 131 to 136 configured to switch an input source of a signal output to the frequency converting and reception low-pass filter unit at the next stage, reception-channel filter units 121 to 128 configured to subject the signals from the frequency converting and reception low-pass filter units 107 to 114 to waveform shaping with a desired frequency characteristic and output the signals, and a filter-bank control unit 13 configured to generate, based on channel information estimated from one or more reception signals, a control signal for controlling the demultiplexed-signal selecting and distributing unit 130 and the selector units 131 to 136.
