摘要
利用矩阵算法对抽样后的非周期信号进行傅里叶变换和傅里叶逆变换,并把这种矩阵算法在MATLAB下进行验证,把它用现场可编程门阵列(FPGA)来实现.实践证明,该方法大大减少了运算的复杂度,且运算的速度也得到了极大的提高.
With matrix algorithm,the sampled aperiodic signal is expressed by Fourier transform and inverse Fourier transform.This algorithm is verified in the MATLAB environment and can be realised via FPGA.It is proved that this method reduces the complexity and increases the speed of calculation significantly.
