Simulated study of realizing discrete convolution and discrete correlation by using fast fourier transform |
| |
| Abstract: | Operation of discrete convolution and discrete correlation will spend too much time to process a signal in time. Aimed at this deficiency, a fast operating method of discrete convolution and correlation is presented in this paper. Computer simulation is carried out and satisfying results are obtained. |
