摘要
针对卫星通信系统中常用的系统卷积码和非系统卷积码进行识别研究,建立基于基本监督矩阵的识别方法,推广了码字同步方法适应各种编码率的卷积码起始位置的判定,给出了BPSK和QPSK调制下的相位模糊的处理方法,实现了卫星通信系统中常用卷积码的识别结果的判定,为卷积码识别技术的工程应用提供了技术基础。
To solve the problem of the recognition of common convolution codes in satellite communication,a method of identifying convolution codes based on fundamental matrix is proposed.The synchronization of the word is extended to adapt to the determination of initiatory location of codes at all kinds of rates, the method for resolution of phase ambiguity at BPSK and QPSK is given, and the recog- nition result of the common convolution codes in satellite communication is checked. This method provides the basic technology for convolution code recognition in projects and applications.
