Design of BPM HF signal based on DDS

Abstract

BPM HF timing service is a kind of economical and convenient timing service method, which uses short wave radio station to transmit and broadcast the standard time and frequency in China. In order to solve the developing and testing problem of BPM applications, we analyze the characteristics of the BPM HF signal and use the direct digital synthesizer (DDS) technology. In addition, field-programmable gate array (FPGA) and digital to analog converter (DAC) are used as the core hardware platform to complete this design. The theoretical calculation and simulation results prove that the design worked well and it can surely promote the development of BPM HF timing technologies.
