Abstract (in Japanese) (See Japanese page) 
(in English) This manuscript reports a procedure and results of probabilistic analysis of non-coherent delay-locked loop (NC-DLL) used in asynchronous DS/CDMA communication with Markovian spreading sequences. Applying the quantization to communication channel noise, we then build a probabilistic network model of the NC-DLL. Moreover, the piecewise constant approximation of a part of internal signal of NC-DLL enables to apply the mean fi eld analysis to the network model. Then, we estimate steady phase tracking error of the NC-DLL. We found that the estimation is validated by numerical simulation of the NC-DLL in channel noise and multiple access interference environments.
