Abstract
In order to meet the requirements of large amount of data, high transmission rate, high reliability of smart ammunitions, and realize the data setting of smart ammunitions, 6 baseband coded formats, such asunipolar non-return-to-zero code, unipolar return-to-zero code, Miller code, Manchester code, mark inversion code and modified miller code, are theoretically analyzed and simulated from three aspects of inductive setting system, such as energy transmission efficiency, power spectrum and bandwidth, and the influence of symbol synchronization on bit error rate, and are compared with the experimental results. The simulation and experimental results show that the modified Miller code with low level gapfactor=0.3 has the better energy transmission efficiency, abundant clock timing information, and lower bit error rate, and it is suitable for the transmission channel; the Manchester code is a kind of self-synchronous phase encoding code, which has a relatively rich clock timing information and a very low bit error rate, and it is suitable for the feedback channel. The laboratory experimental results are consistent with the theoretically simulated results.
