Title:
METHOD AND DEVICE FOR VISUALIZATION OF CODE DOMAIN MULTIPLE CONNECTION SIGNAL IN CODE DOMAIN POWER
Document Type and Number:
Japanese Patent JP3950395
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To visualize both of the power of each of a code or a sub code and the diffusivity, in a graph which expresses the power of the code domain of a CDMA (code domain multiple access).
SOLUTION: The code domain power in a code domain multiple connection signal is indicated in the form of indicating the code power by a two-dimensional graph where an axis Y shows code power and an axis x shows code index. In this two-dimensional graph, the depth being the third axis which represses the diffusivity of each code index is added to make a three-dimensional graph for the code domain power.
