对IQ接收器最重要的两个参数,即I和Q两路分量之间的幅度一致性和相位正交性,可采 用如下办法计算:把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比(即频域内的信号与信号镜像的幅度比) ,通过镜像抑制比和幅度一致性,可求出接收机的I和Q两路分量之间的相位正交性。-IQ receiver for the two most important parameters, namely I and Q components of two-way consistency between the amplitude and phase orthogonality may be adopted calculated using the following method: to I, Q 2 signals, respectively for FFT, to find a frequency domain signal amplitude, can be considered as two-way component caused by the range of 1 the I, Q 2 signals into one complex signal for FFT, the spectrum demand of the received image rejection ratio (ie, frequency domain signal and magnitude of the signal mirror ratio), through the image rejection ratio and extent of consistency, the receiver can be derived I and Q phase between the two-way component orthogonality.

N 元语法分析是一个办法，考察了程序使用字节、 字符或文本字符串的结构。N 元语法分析的一个关键问题是在特征选择爆炸的特点当 N 增加时发生。实验 在本文内代表程序作为操作代码（操作码） 密度直方图所获得的动态分析。A支持向量机用来创建一个参考模型，其中用来评价功能减少，这是两种方法 "的交叉领域"和"子空间分析使用的特征向量"。研究结果表明特征之间的关系复杂和简单统计滤波方法不提供可行的办法。然而，生产特征向量子空间分析 合适的过滤器。
