Title:
RADIO TRANSMITTING APPARATUS, RADIO RECEIVING APPARATUS AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/029458
Kind Code:
A1
Abstract:
A wireless communication system capable of providing both a phase noise canceler
function and a MIMO communication function. In this wireless communication
system, if there exist a plurality of propagation paths, a radio transmitting
apparatus (100) superimposes a pilot signal for phase noise cancellation on
only one of the plurality of propagation paths. A radio receiving apparatus (200)
extracts and uses the pilot signal for quadrature demodulations of the signals
of all of the propagation paths. That is, in the radio receiving apparatus (200),
the pilot signal is extracted by a bandpass filter (210), then amplified by an
amplifier (211), then distributed into two systems by a second distributor (212)
and then used by quadrature demodulation parts (209a,209b) to perform the quadrature
demodulations of the signals of all of the propagation paths.
