摘　　要：删除卷积码构造简单、码率可变、译码灵活的特点使其在自适应编码调制(AMC)技术和多级编码系统(MLC)中得到了大量应用。针对删除卷积码的盲识别问题提出了一种基于生成矩阵特征搜索的快速估计算法,该算法充分利用了删除卷积码生成矩阵的特殊性质,大大减少了搜索范围,仿真结果证实算法有效,且计算量低于文献中已有算法。The punctured convolution code has been widely used in adaptive modulation and coding technology and multilevel coding systems for its characteristic of simple structure, alterable code rate and flexible decoding. A generator matrix characteristic searching based fast parameter estimation algorithm for blind recognition of punctured convolution code is proposed, the algorithm reduces searching range greatly by making a lot use of the characteristic of punctured convolution code generator matrix. Simulation result verifies the validity of the algorithms and computational load is less than the algorithm in literature.
