Title:
METHOD FOR REDUCING INTERFERENCE OF THE ADJACENT CHANNELS IN THE CDMA COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2003/009505
Kind Code:
A1
Abstract:
Present invention discloses a method for reducing and uniformizing interference of the adjacent channels in the CDMA communication system, for making a certain extent of delay control of one forward code channel in respect of other code channel by using cross correlation character of spread spectrum address code. According to interference amount of adjacent channel and mobile station's location, the arisen probability distribution of a certain channel delay amount or the reverse transmission delay of the mobile station is carried out by base station and mobile station or by consulting base station with mobile station. The method of present invention reduces the sensitivity that the area or location of the mobile will be sensitive to interference from adjacent channel, thereby minimizing integral adjacent channel's interference.
