PHASE DETECTION METHOD USING TIMING INFORMATION IN MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a phase detection method using timing information in a code division multiple access mobile communication system, comprising: a first process of calculating a correlation value between a code generated at a receiver and the received signal; and the calculated correlation value A second process of detecting peak values among the extracted peak positions, a third process of calculating whether the timing positions of the extracted peaks and the timing positions of the previous peaks received are different from each other by an integer multiple of the slots; A fourth process of determining whether the third process is performed by the set number of slots of the second process, and if it is determined that the third process is performed by the number of slots, the first number of slots having a peak at the same timing position; A fifth process of identifying a second number, which is the number of slots in which a peak occurs at another timing position, and whether the first number is larger than the second number; And a sixth process of determining whether or not the first number is not greater than the second number, and a seventh process of establishing synchronization again. Therefore, the present invention can reduce the burden of many calculations and field tests required for setting a threshold for phase detection in a mobile communication system.
