摘　　要：在介绍Turbo码编译码原理基础上,针对特定跳频系统,设计了一种Turbo编译码方案。详细论述了该方案中编译码器的设计、建模和仿真过程。该方案中采用MAX-LOG-MAP的迭代译码算法,仿真验证了译码器采用6次迭代可以在保证抗干扰性能的前提下,面向硬件实现计算量适中。因此,该方法具有一定的工程应用价值。A scheme of Turbo coder and decoder in special frequency-hopping system is introduced on the basis of introducing the principle of Turbo coder and decoder.The design,modeling and experiment process of the coder and decoder are discussed.The scheme used iterative decoder arithmetic of MAX-LOG-MAP.Simulation results show that using 6 times iteration for decoder can ensure the anti-jamming performance and the hardware implement calculation moderates.This method can be taken in project and has stated application value.
