LT codes are rate less codes whose code length and dimension can be arbitrarily chosen. It has been shown that they provide considerably better performance by using a message-passing decoding. However, they are not able to achieve good error performance for a noisy channel. Then we propose a concatenated code using outer LT and inner conventional error correcting codes, and its decoding algorithm in which an iterative bounded-distance decoding and soft-decision LT decoding are performed to the inner and outer codes, respectively. The simulation results have shown that the proposed scheme is more effective than a conventional concatenated coding scheme.

LT代码是可以任意选择的代码长度和维度的速率代码。已经表明，通过使用消息解码，它们提供了相当更好的性能。但是，他们无法为嘈杂的频道实现良好的错误性能。然后，我们建议使用外部LT和内部常规误差校正代码及其解码算法提出串联代码，其中分别对内部和外部代码执行了迭代界限限制解码和软抗止动LT解码。仿真结果表明，所提出的方案比常规的串联编码方案更有效。
