METHOD FOR CONSTRUCTING ORTHOGONAL SEQUENCE SETS IN CDMA SYSTEM, CODE WORD GENERATING DEVICE, COMMUNICATION BASE STATION, BASE STATION CONTROLLER, AND WIRELESS COMMUNICATION NETWORK

摘要

The present invention relates to a method for constructing orthogonal sequence sets in a CDMA system, including: step a: selecting natural numbers m and k, m and k satisfying m=2k+4: step b: constructing a 5-spectral value vector Boolean function: step c: constructing 24 orthogonal sequence sets by using the 5-spectral value vector Boolean function: and step d: allocating sequence sets by using the 5-spectral value vector Boolean function; and step d: allocating the orthogonal sequence sets to cells, and causing that sequences in each of the cells are orthogonal with one another, and sequences in each of the cells and sequences in neighboring one of the cells are orthogonal with one another. The constructing method provided by the present invention can increase the number of users in cells, reduce the signal interferences of neighboring cells, and improves the communication quality consequently.
