本文对交错码的工作原理及有关定理进行了简明阐述。介绍了我们研制的交错码的编译码器电路及实验结果。在实践中找到简化求交错码生成矩阵的方法,在交错度很大时优越性更为突出。本文对交错码的纠错能力进行了探讨,得出了交错码纠突发错误能力随交错度增加而成此例增大,纠随机错误能力视不同情况有所区别。通过交错技术的应用,将寻求长而有效的纠突发错误的码简化为求最佳的短码,从而大大简化了构造长码的手续和步骤。实践证明,交错码的编译码器设备简单,易于硬件实现。 综上所述,交错码是一种既能抗随机错误又能抗突发错误的组合信道编码,为遥控指令码,具有明显的优点。
This paper briefly describes the working principle and related theorems of interleaved codes. The codec circuit and experiment results of interleaved code that we developed are introduced. In practice, we find ways to simplify the generation matrix of interleaved codes, and the advantages are more prominent when the interleaving degree is very large. In this paper, the error correction ability of interleaved code is discussed, and it is concluded that the error ability of interleaved code correction and error increases with the increase of interleave rate, and the error correction error varies depending on the situation. The application of interleaving technology simplifies the procedures and steps for constructing a long code by simplifying the search for long and effective error-prone code to the shortest code. Practice has proved that interleaving code codec device is simple and easy to implement hardware. In summary, interleaving code is a combination of channel coding that is both stochastic and burst-resistant, and has the obvious advantage of being a remote control script.
