故该设计综合使用了素因子、Winograd快速傅立叶变换算法
) 摘要: 帧体数据处理是DMB-TH(数字电视多媒体电视广播)传输系统发射端调制的核心部分
) Abstract: The frame-body data processing is the core of modulation in the DMB-TH (Digital Media Broadcast) transmitted system, which used the OFDM (Orthogonal Frequency Division Multiplexing) modulation technology
The module can’t use the sophisticated radix-2 and radix-4 Fourier algorithms directly
By using synthetically the prime factor algorithm and Winograd Fourier transform algorithm, the design method given in this paper realizes the design and simulation of multichannel carrier OFDM with 3780 carrier waves on FPGA (Field Programmable Gate Array)

采用了OFDM(时域同步正交频分复用)调制技术
时域同步正交频分复用
由于此模块不能直接利用现已成熟的基-2和基-4的傅立叶算法
