Abstract本文提出了一种符合HART通信协议的全数字调制解调芯片设计方案。调制部分实现CPFSK调制,对传统的DDS技术进行改进,使其数字部分的杂散性能改善且具有较低的相位连续误差。解调部分实现CPFSK解调,利用数字滤波技术使其具有良好的解调精度和抗干扰能力。性能分析和仿真结果表明,芯片具有良好的性能。
Other AbstractThis paper presents a design scheme of digital modem based on HART communictaion protocol. For the modulation part of the design, traditional DDS technology is improved to implement CPFSK modulation. As a result, the performance of spur and error of digital part are optimized. In the demoduation part, CPFSK demodulation is implemented and digital filters are adopted to get good precision and strong ability of anti-jamming. According to performance analysis and simulation results, the advantages of the design scheme above are proved.
