中文说明：基于kaiser窗的双谱线插值FFT谐波分析，可以得到很精确的幅值、频率、相位估计，已调制信号计算其普相关密度，采用偏最小二乘法，matlab实现了五类灰色关联度模型的计算,实现用SDRAM运行nios，同时用SRAM保存摄像头数据。
English Description：
Based on the Kaiser window double spectrum line interpolation FFT harmonic analysis, we can get very accurate amplitude, frequency and phase estimation, modulation signal calculation relative density of its universal, using partial least squares method, matlab calculation of five gray correlation model, by using SDRAM operation NIOS, also with SRAM save camera data.
