Because of multipath effect, the linear approximation arround tracking error ε=0 of S-currve is no longer suitable. Hence, the is analyzed by using a nonlinear renewal process approach to obtain more exact results of performance. Furthermore, the root-mean-square of tracking error and the mean-time-to-lose-lock(MTLL) are evaluated as a measurement of performance. Finally, the effect of branch offset, interpath delay, interpath power ratio on the performance of the two code tracking loops are investigated. Prof. Char-Dir Chung 鐘嘉德 1995 學位論文 ; thesis 80 zh-TW
