| 摘 要： | 交织器是Turbo码中一个比较重要的部分。通过适当的交织器,可以在不改变Turbo码输入序列码重的情况下增加输出序列的自由距。这也正是Turbo码具有良好性能的来源。本文重点对块交织算法进行了一些探讨。并在两种不同块交织方式、短分组序列的情况下,用计算机Turbo码译码性能进行了仿真,模拟出信噪比-误比特率曲线。

| Abstract: | interweave is a very important component of Turbo - code. By using proper interweaves, we can increase free space of output sequence when we don' t change code of input sequence. This leads to Turbo - code has a excellent performance. On this paper, Block interweaves algorthms are studied. By using computer, we simulate decode performance of Turbo- code when we use two different block as well as short divide- group sequence. At last, we obtain a graph of signal - to- noise bit- error- rate. |
