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.

在Windows下的各种网络编程接口中，Windows Sockets脱颖而出，越来越得到大家的重视，这是因为Windows Sockets规范是一套开放的、支持多种协议的Windows下的网络编程接口。从1991年的1.0版到1995年的2.0.8版，经过不断完善并在Intel、Microsoft、Sun、SGI、Informix、Novell等公司的全力支持下，已成为Windows网络编程的事实上的标准。
在作者利用Windows Sockets规范进行应用开发的过程中，发现这方面的资料很少，特别是缺乏一本全面而实用的专著。为了使广大用户能够充分理解和应用这套规范，我们编写了这本书。本书不但对Windows Sockets 1.1及2.0规范作了较为详尽的介绍，还结合了作者的实际工作，给出了具有实际应用价值的程序实例-In the author standard carries on the application development using Windows the Sockets in the process, discovered that this aspect the material are very few, specially lacks one comprehensive and the practical monograph. In order to enable the user community to understand and to apply this set of standards fully, we have compiled this book. Not only this book 1.1 and 2.0 standards has made a more exhaustive introduction to Windows Sockets, but also unified author s practical work, gave had the practical application value procedure example. Hoped that it can standard and applies the function which to Windows the Sockets in
