感知准则函数是五十年代由Rosenblatt提出的一种自学习判别函数生成方法，Rosenblatt企图将其用于脑模型感知器，因此被称为感知准则函数。其特点是随意确定的判别函数初始值，在对样本分类训练过程中逐步修正直至最终确定。 (Perception criterion function is the 1950s proposed by Rosenblatt, a self-learning discriminant function generation method, Rosenblatt attempt for a brain model of perception, is known as the perception of the criterion function. Its characteristics are free to determine the discriminant function of the initial value, the gradual modification in the sample classification training process until finalized.)

说明：共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。(The Conjugate Gradient method is a method between the steepest descent method and the Newton method. It only needs to use the first derivative information, but overcomes the shortcomings of the steepest descent method and avoids the need for the Newton method to store And the calculation of Hesse matrix and the inverse of the shortcomings, conjugate gradient method is not only to solve large-scale linear equations one of the most useful methods, but also solution for large-scale nonlinear optimization of one of the most effective algorithm. In a variety of optimization algorithms, conjugate gradient method is a very important one. The advantage is that the required storage capacity is small, with step convergence, high stability, and does not require any external parameters.)

软限幅效应,量化阶数及取样间隔对直扩数字匹配滤性能的影响郭南1996 本文以典型的AID变换量化器和改进型抖动噪声量化器为倒t研究几个数字化参数对直接序列扩频(DS／SS)数字匹配滤渡／相关性能(系统的处理增益和误比特率)的影响，给出理论分析及计算机模拟结果用最优化方法研究最佳软限幅问题；指出增加量化比特数与引入抖动噪声相比能更有救地改善系统性能，而且只要采用三比特的量化就能使系统性能接近无穷量他的效果．文中还讨论了取洋间隔以及噪声的归一化带宽对系统性能的影响。本文的结果可为台理设计直扩数字匹配撼披器，相关器提供必要的理论依据。(Soft limiter effect of quantization and sampling intervals on the order of DS digital matched filter performance Guo South 1996 In this paper, a typical quantization AID transform quantization noise and improved jitter inverted t examine several parameters on the digital direct sequence spread frequency (DS/SS) digital matched filter crossing/relative performance (system processing gain and bit error rate) of given theoretical analysis and computer simulation results using optimization method of optimal soft limiter problem pointed out that the increase in quantization bits Number and introduce jitter noise can be more saved than to improve system performance, and as long as the three-bit quantization of the system performance can be substantially infinite amount of his effect. The paper also discusses the fetch interval and ocean noise normalized bandwidth impact on system performance.
