Title: Inintial Cell Search Method of Asynchronous W-CDMA Systems
Inventor: HWANG SANG YUN
IPC: H04B1/7083
Filed: 2000-12-23
Abstract: PURPOSE: A method for searching for an initial cell in an asynchronous W-CDMA system is provided to execute cell searching at a high speed by compensating a change in the relative time difference between a base station and a mobile station. CONSTITUTION: Slot start point information, searched through a slot synchronization process, is handed over not only to the second step but also to the time tracking of a multipath finger. Based on this slot start point information, the time tracking part executes time tracking until one cell searching process is completed. In this case, the time tracking part carries out the time tracking process using a primary synchronous channel code. In case that a pipe line structured cell searcher is used, the rake receiver of a mobile station generally has 3 or 4 multipath fingers. Accordingly, if the number of steps necessary for the cell searcher is 3, a total of 2 time tracking parts are needed. If the number of steps is 4, a total of 3 time tracking parts are required. Therefore, the number of pipe line steps is N, the number of necessary time tracking parts becomes N-1.

Patent KR-20010052536-A (KR)
IPC: H03L7/183
Filed: 1999-06-02
Abstract: A phase-locked loop bandwidth is tuned to a desired level by operating the phase-locked loop in a phase-locked condition at a first frequency and applying a step response to the phase-locked loop by causing the phase-locked loop to begin locking to a second frequency that is different from the first frequency. A parameter is then detected that is related to the applied step response and that is indicative of whether the phase-locked loop bandwidth is at the desired level. The phase-locked loop bandwidth is adjusted, and the steps of operating at the first frequency, applying the step response, detecting the parameter and adjusting the phase-locked loop bandwidth are repeated until the phase-locked loop bandwidth is at the desired level. Where the desired bandwidth level for tuning is not the operational bandwidth, the phase-locked loop bandwidth is further adjusted by a predetermined amount, thereby tuning the phase-locked loop bandwidth to an operational level. The step response may be applied by changing a frequency division value in a feedback path of the phase-locked loop. The detected parameter may be a pulse skip, which indicates that the bandwidth of the phase-locked loop is not yet at the desired bandwidth level.
