基于DSP Builder的星座映射与解映射器设计

Design of constellation mapping and de-mapping based on DSP Builder

提出了一种基于中国地面数字电视广播传输标准的星座映射与解映射器的设计方法。使用DSP Builder的各种模块搭建系统,并利用Signal Compiler生成HDL工程。在完成对所生成工程的优化后,进行相关软硬件仿真验证。实现了32QAM、16QAM星座映射器与解映射器的设计、仿真,并在利用DSP Builder进行DSP系统开发方面进行了深入的探索。

This article describes the design of constellation mapping and de-mapping model based on the Chinese digital terrestrial television broadcasting standard （DMB-TH）. Using the DSP Builder blocks to build the system, and generate the HDL project with the signal compilers. After finishing the hardware customizing, complete the software and hardware simulation. In one hand, this article realizes the design of 32QAM and 16QAM constellation mapping and de-mapping, and also make deep explore in developing the DSP system based on DSP Builder.
