摘要

虽然采用信念传播(BP)算法可以解决噪声信道上的LT译码问题，但系统性能不是很好。本文介绍了一种提高LT软译码系统性能的方法。该方法使用不同百分比的编码数据包的系统连接。仿真结果表明，所提出的改进LT码方案优于传统的LT码方案。

Modified LT coding with systematic connections

Although belief propagation (BP) algorithm can be used to solve the problem of LT decoding on noisy channels, the system performance turns out to be not very good. In this paper, we introduce one method to improve the system performance of LT soft decoding. The method is using different percent of systematic connections of encoded packets. Simulation results reveal the advantage of the proposed modified LT code over the conventional LT code scheme.
