【摘要】 基2级联基2平方单路延时反馈结构为基础的512点FFT处理器,在使用和Altera Megacore7.1差不多资源的情况下,精度提高了14dB,最高工作频率能够达到100MHz以上,完全能够满足DMT调制在精度和实时性上面的要求。更多还原

【Abstract】 This FFT processor is realized based on the structure of Radix-2 cascaded with Radix-22 . We use almost the same resources as Altera Megacore 7.1. However, this processor’s precision is 14dB higher, and the maxinum frequency is above 100MHz which is totally meet the precision and real-time request in DMT de(modulation).更多还原
