摘要
结合工程实践,提出一种适用于OFDM系统的128点FFT处理器的FPGA实现。FFT处理器使用VerilogHDL语言进行描述,采用同步流水线结构,具有由定点引起的量化误差低的特点,并且可以连续实时地处理高速数据流。在Xilinix的FPGA上得到验证,且有利于移植到ASIC。能满足高速实时的OFDM系统的需求。
A 128 point FFT processor of OFDM system is presented,according to practical project.The design is described with Verilog HDL,and has lower fixed-point calculation quantization error;methods of pipeline and synchronization are used for this design to meet OFDM systems of high-speed and real-time.The design is performed with synthesized and place and route in ISE 8.2i of Xilinx tools.
