The Implementation of HF Broadband Receiver's Channelization Based on DSP
Niu Zhong-xia · Journal of Information Engineering University · 2005
The traditional HF broadband receiver mainly uses the hardware for channelization, and can't process many broadband signals timely. The paper presents that software is combined with hardware for the HF Broadband Receiver's channelization, adopts the arithmetic of multi-phase filter that has wide dynamic range and efficient implement, uses special DSP software for simulation of channelization, shows the channelization results of several ideal signals by the multi-phase banks arithmetic, gets and analyzes the result. The paper introduces the hardware platform of HF broadband receiver's channelization, explains the design and function of the software-channelized DSP data-flow processing module, and describes the working process of HF broadband receiver's channelization based on DSP from the whole frame.
