本文介绍了数字接收机ICS554的结构,使用其中的FPGA完成频谱分析处理器的设计工作。整个设计采用流水方式,提高了系统时钟频率,对数据完成了缓存、加窗、快速傅立叶变换处理。实验结果表明此处理器高速地实现了频谱分析功能,满足实时信号处理要求。

This article introduces the structure of the digital receiver ICS554, and accomplishes the design of FFT processor based on FPGA. By using the pipeline architecture in the whole design, the frequency of the system clock increases, and put the data into three operations which include storage, multiplying window, performing FFT. Result of the experiment proves that the processor implements the function of spectrum analysis at a high speed and satisfies the request of commonly real-time signal processing.
