FRAME SYNCHRONIZATION DEVICE USING SYNCHRONIZATION CHANNEL OF CDMA COMMUNICATION SYSTEM AND FRAME SYNCHRONIZATION METHOD

摘要

One base station transmitter is the super frame period for including a synchronizing channel, multiple first synchronizing channel frames from super frame period segmentation, the first synchronizing channel frame, each there is a first stage, and a CDMA communication system of multiple customer channel frames is divided from the first synchronizing channel frame, customer channel frame, each there is a second stage, wherein synchronous channel signal is transmitted by customer channel frame. Base station transmitter includes a generation circuit synchronization channel signal; In one synchronous channel signal of a channel spreader for channel spread except the customer channel frame in every one first synchronizing channel frame with the first orthogonal code and the channel spread synchronous channel signal in the remaining synchronizing channel frame with second orthogonal code in a leading synchronizing channel frame.
