摘　　要：本文在扩展卡尔曼滤波、混沌信号模拟调制,以及数字纠错编码的码距离度量等思想的基础上,设计和实现了一套基于混沌的模拟纠错编码/解码算法。仿真结果表明在低信噪比情况下,该算法有较强的纠错能力,优于传统的分组交织纠错编码。On the basis of the extended Kalman filtering, the analog chaotic modulation, and the distance measurement of digital error-correcting coding, an algorithm of analog error-correcting coding/decoding based on chaos is designed and realized in this paper. The simulation results indicate that the algorithm has a better ability in error-correction under a higher noise environment, and outperforms the traditional block interleaving error-correcting coding.
