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.)

pedometer
本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)
