接收机中频数字化模块设计

文中介绍接收机全数字化设计中的中频数字化模块设计方案。模块的核心部分包括模数转换和解调部分,通过DSP芯片对系统进行合适的控制与设置,对中频信号进行数字化解调接收。本系统可用于卫星信号数字接收机,同时对于接收机中频数字化给出通用的方案。

Design for IF digitizing used in digital receiver

In this paper,a design for digitizing intermediate frequency(IF) which is used in digital receiver. The core of the design including an analog/digital convertor and a demodulation part can receive and demodulate the IF signal with proper setting and controlling of a digital signal processor. This system can be used in satellite digital receiver. It is also provided as a common solution of digitizing intermediate frequency of receiver.
