Title:
METHOD FOR CONSTRUCTING ORTHOGONAL SEQUENCE SET IN CDMA SYSTEM, CODEWORD GENERATION DEVICE, COMMUNICATION BASE STATION, BASE STATION CONTROLLER AND WIRELESS COMMUNICATION NETWORK
Document Type and Number:
WIPO Patent Application WO/2019/128464
Kind Code:
A1
Abstract:
The present invention relates to a method for constructing an orthogonal sequence set in a CDMA system, comprising: 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: using the 5-spectral-value vector Boolean function to construct 24 orthogonal sequence sets; step d: allocating the orthogonal sequence sets to a cell, enabling the sequences in the cell to be orthogonal to each other, and enabling the sequences in the cell to be orthogonal to the sequences in neighboring cells. The constructing method provided by the present invention can increase the number of users in a cell, reducing signal interference of neighboring cells, improving the communication quality.
