摘要: 为满足灵巧弹药大数据量、高速率、高可靠性的装定需求,实现灵巧弹药的数据装定,针对感应装定系统的信道特性,从能量传输有效性、功率谱与带宽、码元同步误差对误码率的影响3个方面, 对单极性不归零码、单极性归零码、密勒码、曼彻斯特码、传号反转码、变形密勒码6种数字基带码型进行理论分析、仿真和实验室试验。仿真与试验结果表明:低电平间隙因子为0.3的变形密勒码具有很好的能量传输有效性、较为丰富的时钟定时信息和较低的误码率,适合选做发送信道的基带码型;曼彻斯特码是一种自同步相位编码,具有丰富的时钟定时信息、较低的误码率,适合选做反馈信道的基带码型;实验室试验结果与理论仿真结果具有一致性。

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 as unipolar 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.
