Abstract (in Japanese) (See Japanese page) 
(in English) Optical orthogonal frequency division multiplexing (OFDM) has been actively considered for high capacity optical transmission not requiring optical dispersion compensation. In OFDM the transmitter and receiver IQ imbalance cause image interference that is known to be problematic in high capacity systems using high order modulation such as 16QAM. In this work we demonstrate a hybrid IQ imbalance compensation method based on orthogonal training symbols and image reduction algorithm, and confirm improved performance in optical OFDM by simulation. We verify the results with a 16QAM 27.3 Gbps direct detection (DD)-optical OFDM transmission experiment, where after 320km SSMF, 3.5 dB OSNR performance improvement is achieved. We have also confirmed improved performance by the proposed compensation method under carrier frequency offset in a 50 Gbps DD-OFDM experiment.
