本文讨论了实带通信号在二阶非均匀采样下的快速频域搬移、恢复,即用FFT方法将实带通信号恢复到两倍带宽(2B)内的复解析信号,而幅度和相位保持不变,最后经过简单的运算,得到原始频率。计算机模拟证实了上述方法。
In this paper, we discuss the fast frequency-domain moving and recovery of real-band signals under second-order non-uniform sampling, that is, recovering the real-band signals to complex analytic signals within twice bandwidth (2B) Unchanged, and finally after a simple operation, get the original frequency. Computer simulation confirmed the above method.
