| Abstract: | An arithmetic to calculate correlation of two long sequences is introduced by using a fast correlation method,and the FFT coefficient table with DSPLIB library function is designed.At last two 1024-dot real sequences' linear correlation operation was accomplished.Compared with the direct correlation method,this method is easier,rapider and more practical. |
