The HF Broadband Receiver is a focus of research in the domain of HF receiving in recent years, and the receivers channelization is one of the very important parts. The traditional HF Broadband Receiver mainly uses the hardware for channelization, and can't process many broadband signals timely. The paper presents a method, in which the software is combined with hardware for the HF Broadband Receivers channelizafion, adopts the arithmetic of multi-phase filter that has wide dynamic range and efficient implementation, uses two different software for simulatiing the channelization, shows the channelization results of several ideal signals by the general filter banks arithmetic and the multi-phase banks arithmetic, and analyzes the result obtained. When the DSP software simulates the channelization, the condition of hardware must be considered. The code performance analysis tools of VisualDSP + + estimate the performance of code, and improve the real-time signal processing.
