Title:
DEMULTIPLEXING DEVICE, MULTIPLEXING DEVICE, AND RELAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/125600
Kind Code:
A1
Abstract:
The present invention is provided with reception analog filters (13-n, where n = 0, 1, or 2) that extract a desired signal from a received signal, A/D converters (14-n) that convert the signals that have passed through the reception analog filters (13-n) into digital signals, demultiplexing units (15-n) that demultiplex the digital signals converted by the A/D conversion units (14-n) into m number of signals, receiving-side compensation units (16-n) that digitally compensate the analog characteristics of the reception analog filters (13-n) for the m number of signals that have been demultiplexed by the demultiplexing units (15-n), and multiplexers (19-n) that multiplex the m number of signals that have been digitally compensated by the receiving-side compensation units (16-n). The receiving-side compensation units (16-n) further demultiplex, into k number of signals, each of the x number of the digitally compensated m number of signals that were not sufficiently compensated, digitally compensate the analog characteristics of the reception analog filters (13-n) for each of said k number of signals, and multiplex the digitally compensated k number of signals.
