摘要: 随着射频信号在高速传输领域的广泛应用,传统分立式射频架构面临资源与性能瓶颈,而集成度高、功耗低的RFSoC(Radio Frequency System on Chip,射频片上系统)成为解决该问题的重要方向。围绕国产化RFSoC的滤波优化处理展开研究,提出一种利用SUPERDSP对国产化RFSoC采样后的高速数据进行滤波的方案,实验证明该方案在滤波效果与传统FIR滤波相当的基础上,能大量降低DSP等硬件资源的用量,为国产化射频系统的优化设计提供理论与实践参考,具有重要的工程意义。

Abstract: With the wide application of RF signals in high-speed transmission fields, traditional discrete RF architectures are facing bottlenecks of resource and performance problems, while RFSoC with high integration and low power consumption has becoming a good solution. This paper focuses on the research of filter optimization of domestic RFSoC, and proposes a project for the filtering of high-speed data after the sampling of domestic RFSoC using SUPERDSP. Experiment has shown that this project has the same performance of traditional FIR filtering, but also a substantial reduction of hardware usage. It provides theoretical and practical references for the optimal design of domestic RF systems, and has great significance on engineering.
Key words : RFSoC;SUPERDSP;filtering optimization;resource conservation

引言

数字接收是数字信号处理中的重要模块之一。近年来,随着硬件技术发展,数字传输的载频频率越来越高,射频信号逐渐成为大数据量、高速传输时的优选信号。射频信号的接收相比低频信号更加困难,对系统的要求也更高。传统分立式射频架构面临带宽受限、功耗高、复杂度等问题[1],而RFSoC通过单片集成ADC(Analog to Digital Converter,模数转换器)、DAC(Digital to Analog Converter,数模转换器)、FPGA(Field Programmable Gate Array,现场可编程逻辑门阵列)等模块,在保证射频采样的前提下,拥有较高的集成度,可大幅减少占板面积,降低功耗,并优化部分PCB(Printed Circuit Board,印制电路板)布线,具有良好的应用前景和较高的实用价值[2]。

本文将在某国产化型号板卡的设计要求下,聚焦RFSoC采样后的滤波处理等问题,提出一种基于国产化RFSoC的滤波优化方案,并在硬件平台上进行了实现。实验结果表明该方案在保证对于8通道射频宽带信号采样数据的滤波效果的同时,相比传统架构更节省DSP(Digital signal Processing,数字信号处理)资源,同时对带外信号抑制达到73.5 dB,具有较高的工程应用价值。
