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.

为什么同样颜色的光有的能色散有的不能?为什么只有感受三种颜色的椎细胞(红、绿、蓝)，而这三中波的波长都比紫光波长长，我们却能看到紫色？我认为把什么人眼的细胞分为椎细胞，柱细胞，和分别感受不同基本颜色的光的细胞纯属胡说八道-Why do some of the same color of light dispersion and some can not? Why only three colors of the feelings of vertebral cells (red, green, blue), and three Wave~s wavelength are longer than the wavelength of perpue, we can see the purple ? I think that what the human eye cells into cells of vertebral column cells, and the feelings were different basic colors of light cells is purely nonsense.
