摘要
本文使用MATLAB软件,提出了基于Simulink的仿真实验平台,搭建了使用多级编码方案的DRM数字调幅信道编码仿真系统。通过对DRM使用标准映射方式下的多级编码的介绍,阐述了编码与调制技术结合的特点,说明了其信道编码的主要技术方案。使用所设计的仿真系统与不采用编码调制的普通编码和调制方案的比较,说明了DRM信道编码有着较低的误码率的优越性。同时该仿真系统可设置不同的卷积编码方案和不同的码率,为能够更好的进行DRM信道编码研究分析提供了软件仿真平台。
Using Matlab,this paper designed a simulation system of DRM channel coding which use multi-level coding based on Simulink.It elaborated the feature of the combination of channel coding and modulation.This paper explained the advantage of DRM channel coding that had a low bit error rate,via the introduction of the coding scheme and the comparison with common coding and modulation.Meanwhile,the simulation system can be used as a simulation software platform for research and analysis of DRM channel coding,for the different convolutional coding and coding rate can be set in it.
