Abstract (in Japanese) (See Japanese page) 
(in English) Multilevel polarization shift keying (MPolSK) is an optical modulation method, in which state of polarization changes according to transmission data.When either transmitter or receiver is not fixed, polarization axes mismatch is caused. It significantly degrades communication performance. To overcome this problem Multilevel differential PolSK (MDPolSK) was proposed, in which we perform differential encoding on a successive pair of transmission symbols. Because the decoding process needs two successive symbols and they are affected by independent noise, MDPolSK is sensitive to noise. To reduce the influence of the noise in MDPolSK, we proposed a method to estimate inclined polarization axes. When polarized light propagates over atmospheric turbulence channel, the light intensity fluctuates.However, we ignored the change in state of polarization by the fluctuation in past reports. In this paper, we investigate MDPolSK with estimation of inclined polarization axes over atmospheric turbulence channel and evaluate its symbol error rate. The intensity fluctuation is modeled as lognormal distribution.
