DEMULTIPLEXING APPARATUS, MULTIPLEXING APPARATUS, AND RELAY APPARATUS

摘要

A relay apparatus includes a reception analog filter that extracts a desired signal from a received signal, an A/D converter that converts the signal after passage through the reception analog filter into a digital signal, a demultiplexing unit that demultiplexes the digital signal converted by the A/D converter into m signals, a reception-side compensating unit that digitally compensates for an analog characteristic of the reception analog filter with respect to the m signals demultiplexed by the demultiplexing unit, and a multiplexing unit that multiplexes the m signals digitally compensated by the reception-side compensating unit. The reception-side compensating unit further demultiplexes each of x signals not sufficiently compensated among the digitally-compensated m signals into k signals, digitally compensates for the analog characteristic of the reception analog filter, and multiplexes the k signals after the digital compensation.

主权项

1: A demultiplexing apparatus comprising:
a reception analog filter that extracts a baseband signal from a received signal; an analog-digital converter that converts the baseband signal extracted by the reception analog filter into a digital signal; a demultiplexer that demultiplexes the digital signal converted by the analog-digital converter into a plurality of demultiplexed signals; a reception-side compensating unit that digitally compensates for an analog characteristic of the reception analog filter with respect to the demultiplexed signals demultiplexed by the demultiplexer, demultiplexes each of one or more demultiplexed signals among the digitally compensated demultiplexed signals into a plurality of signals, digitally compensates for the analog characteristic of the reception analog filter with respect to the demultiplexed signals, and thereafter multiplexes the demultiplexed signals; and a multiplexer that multiplexes the demultiplexed signals digitally compensated by the reception-side compensating unit.
