Due to non orthogonality of signature sequence, performance of lineardetector is much less than that of the optimum detector that is nonlinear.
最佳多用户检测器是非线性检测器,特征码不完全正交时,线性检测器很难逼近最佳检测器。

The basic concept of a coordinate logic is firstly introduced and a novel non-linear edge detector using multi-structure element is proposed for the application of edge detection.
