一种基于正交投影的部分自适应方法

Partial Adaptivity Based on Orthogonal Projection

本文提出了一种基于正交投影算法的部分自适应方法。这种方法与基于特征结构法和最小功率法的部分自适应方法不同，它不需要知道有关干扰信号的先验知识或者对此作出假设，也不涉及复杂的特征值分解或线性多元参数优化问题，因而相应的算法在变化的信号环境中具有相当的稳健性，另外也具有算法简单、响应速度快的特点。文中给出了相应的计算机模拟结果。

A partially adaptive approach based on orthogonal projection was proposed in this paper.Unlike these approaches based on eigenstructure or output power minimization,knowledge of jammer enviroment,eigenvalue decomposition or no-linear optimisation computation are not required.Thus, its algorithm is robust ,simple and fast.Simulations illustrate the effectiveness of this approach.
