The Application Research And Implementation Of BOC Modulation On The Measure Of Time Transfer

Introduced the definition of time transfer and the advantage using optical fiber as medium in time transfer,the definition and spectral characteristics of BOC are present, the method of two-way satellite time transfer and accurate time transfer method using bidirectional wavelength division multiplexing are introduced,and the problems in technology and development direction in high-precision time transfer are discussed; Have a simple introduce to the code style used in time transfer.We also make some analysis about the BOC modulation. According to the advantage of BOC and the technical requirements of time transfer via optical fiber, we think the accuracy will be better when used BOC modulation. We stimulate the modem which is designed using software,design and produce a hardware experimental platform,realize the BOC modulation and demodulation,and test the stability of second pulse,We get a satisfactory result.
