DVB-T中的FFT设计与实现

Design and realization of the FFT processor on DVB-T

文章首先对DVB-T系统的概念和应用进行了阐述,接着重点对其中的FFT模块进行研究。由于DVB-T系统存在2K/8K模式,为方便起见,我们选择采用2K模式进行FFT模块的设计与实现,包括算法实现、系统架构设计、FPGA实现、仿真。最后对仿真结果进行了分析。

This paper brings forward a DVB-T system,and represents its conception and application.Then we make a detail research of FFT module on DVB-T.DVB-T system contains two kinds of modules which are 2K module and 8K module.In order to make the design convenient, we choose 2K module to do the work which include arithmetic realization、system architecture design、FPGA realization、emulation.At last,we will analyse the result of the emulation.
