Abstract针对空间数据系统咨询委员会(CCSDS)下行遥测(TM)传输帧识别技术的应用,利用校验多项式对(2,1,6)卷积码进行了识别,提出了基于编码模式串匹配的方法对卷积码进行节点同步;利用链路层帧长特征对Reed-Solo- mon(255,223)编码的交织深度进行初始判别,并采用伽罗华域傅里叶变换对识别结果进行验证.对识别算法进行了仿真,讨论了不同误码率情况下的识别结果.仿真实验结果表明,算法可对TM传输帧进行有效识别.
Other AbstractA recognition method of downlink telemetry(TM)transfer frame of consultative committee for space data systems(CCSDS)is presented.A detection algorithm of(2,1,6)convolutional code based on check polynomial is examined.A node synchronization technique based on pattern-matching is proposed for convolutional code.The frame length is used to roughly judge the interleaving depth of Reed-Solomon (255,223),then the galoias field Fourier transform is introduced to verify the recognition results.Simulation is given according to different bit error rates and the TM transfer frame can be recognized effectively.
