基于短帧的Turbo码迫零问题研究

一般来说，在交织长度很深时，无需考虑turbo码的迫零问题。但是对于短交织(短帧)，迫零影响必须考虑。在概述turbo码编译码原理的基础上，通过带宽和性能的折衷考虑，得出不同范围内短帧的迫零方式，并进行了仿真和验证。

Research on Termination Schemes of Short Frame Turbo Codes

Generally speaking, the choice of turbo-codes termination schemes is not crucial for the error correcting performance of long frames . But termination schemes have the important effects on the performance of short frames. On the basis of describing the principle of turbo coding and decoding , this paper educes various termination schemes of different range short frames by eclectically taking into account bandwidth and performance, and gives the simulatio- n results and confirmation.
