Abstract(in English) In this paper, as binary modulation schemes, the differentially on-off keying (DOOK) system, which can achieve anti-background noise capability and high data transmission efficiency, is considered. In order to solve the synchronization slip, the synchronization signal-embedded frame DOOK system with has been investigated. The correlation value between the output signal of the differential detector and the reference signal deteriorates by ${-1,0,1}$-synchronization pattern. One of the serious problems encountered in the optical-wireless framed DOOK system is to overcome the synchronization slip problem. In this paper, an optical-wireless framed DOOK system embedding ${-1,+1}$-synchronization signal pattern is proposed. Moreover, theoretical formulas of detection and false alarm probability are derived. The detection probability taking into account false rate is evaluated under the optical-wireless channel with scintillation and background noise. Consequently, in the evaluation of detection probability taking into account false alarm rate, the proposed system is 1.8[dB] better than the conventional system when the probability of false alarm achieves $10^{-3}$. Moreover, the evaluation of detection probability taking into account false alarm rate achieves 1 when logarithmic variance of scintillation is 0.01, background noise is less than $-45$[dBm] and transmission power per bit is $-43.8$[dBm].
