LSE 算法估计载波频率和相位 matlab
应用LSE 算法估计载波频率和相位，又称为锁相环。使用初值和迭代算法，估计频率和相位值，并根据估计出的频率和相位值画出估计得正弦波。将正弦波真值和估计值画在同一个图中，每更新一次，重新绘制两个波形，最终需要画出演示视频中的效果：估计出的波形逐步靠近真正的波形。(Use the initial and iterative algorithm, estimate the frequency and phase values, and according to the estimated frequency and phase values estimated to have drawn the sine wave. The sine
Wave true value and the estimated value of the painting in the same figure, each updated once repainted two waveforms eventually need to draw the demo video effect: estimate
Count out the true waveform waveform gradually close.)
