| 摘 要： | 提出了一种为Turbo码而设计的交织器.相对于那些需要存储整个交织深度的交织器来说,这种交织器由于采用奇偶对称映射方法,因此只需记忆一半的交织深度,从而可减少近50%的存储单元,并且这种映射的约束对Turbo码的性能无损,这在硬件实现时是非常重要的.

| Abstract: | This paper presents a new structure of interleaver that saves 50% memories relative to conventional ones. By swapping the odd and even positions, the interleaver has the property of symmetry, and the constraints on the mapping didn't deteriorate the performance of the interleaver. This is important in hardware implementation. |

| Keywords: | Turbo code interleaver odd even symmetric mapping |
