Title:
分波装置、合波装置および中継装置
Document Type and Number:
Japanese Patent JP5575149
Kind Code:
B2
Abstract:
To obtain a demultiplexing device that can reduce power consumption. The demultiplexing device includes frequency-conversion and reception low-pass-filter units 101 to 114 that perform a frequency converting process and a low-pass filtering process for causing a signal to pass through a desired band, perform downsampling to reduce a sampling rate to half of a data rate of an input signal, and output the signal, reception channel-filter units 121 to 128 that waveform-shape a signal with a desired frequency characteristic and output the waveform-shaped signal, a filter-bank control unit 13 that generates a clock control signal for supplying a clock to frequency-conversion and reception low-pass-filter units and reception channel-filter units corresponding to signal passage bands, based on channel information, and a reception-clock supply unit 14 that supplies a clock to frequency-conversion and reception low-pass-filter units and reception channel-filter units corresponding to signal passage bands, based on the clock control signal.
