Abstract (in Japanese) (See Japanese page) 
(in English) In visible light communications, an optical-wireless code shift keying(CodeSK) system using PN-code composed of non-negative signal has been considered. In order to realize an optical-wireless CodeSK system, it is important to design a PN-code synchronization tracking method. The authors have proposed the delay locked loop(DLL) for CodeSK system using concatenated modified pseudo orthogonal M-sequences. In this report, jitter in DLL and bit error rate(BER) performance which considers jitter are analyzed in the optical-wireless communication environment. As a result, it was found that at $BER=10^{−4}$, the proposed method can suppress the deterioration from ideal performance to 0.27 [dB] for equivalent noise band coefficient $k_e=0.01$, and to 1.4 [dB] for $k_e=0.1$.
