摘　　要：Turbo编译码技术因其优越的性能在无线通信领域得到广泛地研究和应用。介绍了Turbo码的编译码原理和迭代译码结构,仿真了不同交织长度、迭代次数和接收码元的量化对Turbo译码性能的影响,并基于航空通信系统应用对特定参数的Turbo码进行工程实现。仿真结果和工程实现结果均表明:所选取的Turbo码实现简单,性能优异,对航空通信系统中Turbo码的选取具有重要的指导意义。Turbo encoding and decoding technology has been widely studied and applied in the field of wireless communication because of its excellent performance. This paper introduces the structure of the basic encoding and decoding of Turbo code and structure of iterative decoding, the effects of interleaving length and iteration number and the quantization of the received Turbo codes on the performance of Turbo decoding are analyzed. And based on the application of aeronautical communication system, Turbo codes with specific parameters are applied to the project. The engineering implementation results are compared with the simulation results. Simulation results and engineering implementation results show that the Turbo codes selected are easy to realize and have excellent performance and important engineering guidance to aeronautical communication system.
