IFFT/FFT Algorithm Research And FPGA Implementation Of ADSL Transmission System

Now the ADSL has already rolled up the world-wide locations, getting the overall universality in China. But there still exists the baud rate low etc. blemish in the development. The processor of FFT is an ADSL core, its function affects the ADSL to deliver the function directly, so the design of the processor of FFT performing highly has been a hot research problem in the control theory and control engineering area.This text mainly carry on the research on the calculate way of the FFT and the hardware realizations. the main work is as follows:1, Analyzing the ADSL system ,complete the part design of the AFE and DSP.2, Set out from the factor of the influence FFT speed, carry on the FFT theories research , and give a excellent design to perform FFT.3, Analyzing and comparing the processor of FFT currently, Made sure the chip of PLD to design the processor of FFT. After analyzing the hardware characteristic of the chip, complete the design of the new FFT...
