Abstract (in Japanese) (See Japanese page) 
(in English) MIMO-OFDM is a promising technique for achieving higher
channel capacity and/or higher communication quality by using multiple antennas
at the transmitter and receiver.
The use of OFDM per each antenna
preserves the robustness against frequency selective
fading channels and achieves higher spectral efficiency.
However, the well-known drawback of the OFDM is the fact that it has
very high peak-to-average power ratio (PAR).
The clipping and filtering (CAF) is a simple method
of reducing PAR, but it introduces severe nonlinear distortion
that may considerably degrade the overall performance.
In this paper, we study the performance of MIMO-OFDM system
with CAF and investigate the improvement achieved by the use of
clipping noise cancellation (CNC).
