Title: Base station synchronizing method
Inventor: RUDOLF MARIAN
IPC: H04W92/00
Filed: 2001-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for synchronizing adjacent base stations by using a system having a satisfactory self-correlation characteristic over a wide selection range and length. SOLUTION: The synchronizing system is constituted of two Golay complementary systems A and B which are time-base multiplexed. Guard times GP1 to GP3 are added to the front and the back of the respective systems. The system is transmitted by one base station and is received by the adjacent base station. At the time of reception, the synchronizing system is correlated with the copy of the system A and the copy of the system B. A correlation result with the system A is delayed so that it is time-base arranged with that of the system B and they are added. The Dirack peak is obtained when the copies of A and B are arranged with the corresponding system.  Since guard times GP1, GP2 and GP3 exist, the systems A and B become sure that they are not overlapped with the corresponding complementary copies, namely, B and A in a time window where a time array position is set to be a center at the time of correlation.
