| 摘 要： | 基于李道本等人提出的代价函数，在特定的约束条件下，利用酉变换方法，提出了两个约束化均衡算法。这两种均衡算法是传统的直接梯度算法和共轭梯度算法的改进方法。这两种约束算法是在Householder变换下或GiVen平面旋转变换下获得的，它们完全不同于前人的各种线性约来自适应算法，这两种算法的计算复杂度是可以接受的。计算机仿真结果验证了这两种变换域算法的性能。

| Abstract: | Two constrained algorithms were derived based on a superexcellent cost function such as the steepest decent algorithm(SD),and the conjugate gradient algorithm(CG),subject to a new constraint condition,which are the modified versions of the conventional algorithms.They are both implemented in unitary transform domain,which are completely different from the previously constrained adaptive filtering algorithms .The computa tional com plexities of the constrained algorithms proposed are acceptable.Simulated computa tions show their perfor-mance. |
