DSP的软件信道化接收机的设计与实现

Design and Implementation of a Software-channelized Receiver Based on DSP

基于传统信道化接收机以硬件划分信道为主,无法实时处理大量的宽带信号,提出了软件结合硬件来实现宽带信号中子信道的划分;采用多相滤波算法实现信道化,介绍了软件信道化接收机实现的硬件平台,对该接收机硬件设计中每个电路模块的功能及实现分别作了说明,并从整体上描述了软件的信道化接收机的工作流程。

The traditional channelized receiver uses mainly hardware for channelization, and can′t process many broadband in real time. This paper suggests that the software is combined with hardware for the channelization, and adopts the arithmetic of multi-phase filter to implement it, and introduces the hardware platform of software-channelized receiver, explains its function and implement ation of each part in the hardware design of receiver. The working process was described from the whole system view.
