Title:
WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/125570
Kind Code:
A1
Abstract:
A wireless communication system and a wireless communication apparatus wherein
even when there exist transport signals of different communication schemes
in the same frequency band or there exist a plurality of transport signals of the
same communication scheme, communication using such transport signals can
be performed with no interference with each other. There are included a first
wireless communication apparatus (101), a second wireless communication apparatus
(104), and a third wireless communication apparatus (102). The third wireless
communication apparatus (104) includes a fixed bandpass filter (701) and a variable
bandpass filter (705). A first wireless communication signal (106) includes
control information for designating a variable passband in the variable bandpass
filter (705). The control information is provided to the variable bandpass filter
(705), thereby causing the variable bandpass filter (705) to selectively pass
the first wireless communication signal, while eliminating a second wireless
communication signal.
