摘要
通过对网络非线性失真的研究,探索验证了一种利用FFT来测试网络非线性失真的新方法。叙述了用低成本Cy-clone系列FPGA实现基4结构1024点FFT(快速傅里叶变换)算法的方法,从而得出其失真度。针对其设计所而临的问题提出了Altera公司的基于IP核的SOPC解决方案。
Through the studying of the nonlinear distortion of network, a new method based on the FFT to test the nonlinear distortion of network is tested .It describes an implementation of 1024 Points FFT algorithm using radix 4 structure based on the low-cost FP- GA of Altera （Cyclone serials）,thus obtains its distortion .It has gave the solutions proposed by Ahera Corporation aiming at the problems in design that is SOPC based on IP Core .
