摘　　要：文中叙述了一种基于FPGA的64点采用基4碟形结构的FFT(快速傅立叶变换)的设计以及在新一代5G通讯系统OFDM(正交频分复用)中的应用;每一级的设计结果与Ximulinx的仿真结果进行比较,以保证FFT设计过程的正确性;仿真结果表明该方案设计的FFT具有精度高,速度快,占用资源少等优点。This paper describes the design of tadix-4 FFT based on FPGAand its application in OFDM system known as the new 5G communication system. The simulation result of the design for each grade is compared with the simulation result of ximulinx, thus to make sure the correctness in the design process. The simulation result indicate that this project has many advantages such as high precision, fast speed and less occupation.
