摘　　要：在对传统串行级联码性能进行分析的基础上,提出了在COFDM传输系统中的Turbo码替代方案,并结合具体信道进行性能仿真,通过对其性能的比较,提出了一种优化的设计方案并论证了该方案的可行性。Based on the analysis of the traditional concatenated code, an improved scheme is presented in this paper,whose performance is simulated by the Matlab in the special channel. Finally, an optimized design is proposed and its feasibility is also tested by experiments.
