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.

This book shows you how to write programs that run under Microsoft Windows 98, Microsoft Windows NT 4.0, and Windows NT 5.0. These programs are written in the C programming language and use the native Windows application programming interfaces (APIs). As I ll discuss later in this chapter, this is not the only way to write programs that run under Windows. However, it is important to understand the Windows APIs regardless of what you eventually use to write your code. -This book shows you how to write programs that run under Microsoft Windows 98, Microsoft Windows NT 4.0, and Windows NT 5.0.
