Researchers from the NTSC Completed the Verification of the New Shortwave Time Signal Modulation Scheme Based on Chirp

In order to enhance the anti-interference receiving ability of shortwave time signals and improve the performance of shortwave time service system, researchers from the National Time Service Center(NTSC) of the Chinese Academy of Sciences(CAS) began the research on the new system of shortwave time signals. The researchers proposed to introduce spread spectrum technology into BPM shortwave time service system and achieved a new shortwave time signal modulation scheme (DCTCDM scheme) based on linear frequency modulation (Chirp).
