| 摘 要： | 中频接收机的输入信号为一个带通信号，在进行数字处理前，必须先对其进行数字化变换，即将一个实信号变成两个正交数字序列。变换后的数字信号具有数字化前模拟中频信号的全部相位和幅度信息。本文主要探讨如何利用软件无线电技术实现中频接收机的数字采样及正交变换。

| Abstract: | The input singnal of intermediate frequency reciever is a band-pass signal and the figure must be transformed before being processored,i.e.one real signal is turned into two perpendicular numeric sequences.The transformed digital signal has the total phase and value of the intermediate frequency signal before it is digitalized.How to realize the digital sampling and perpendicular transform of intermediate frequency reciever using software radio-technology is discussed chiefly in this paper. |
