使用matlab进行边缘提取，更加深刻的理解canny算法应用(Using matlab to edge extraction, a more profound understanding of the application of canny algorithm)

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)

图像处理的梯度算法，本身还行，有兴趣的可以研究一下(Gradient image processing algorithms, their okay, are interested can look at)

Specify the condition to stop the decoding iterations as one of Maximum iteration count | Parity check satisfied . The default is Maximum iteration count . When you set this property to Maximum iteration count , the object will iterate for the number of iterations you specify in the Maximum Iteration Count property. When you set this property to Parity check satisfied , the object will determine if the parity checks are satisfied after each iteration and stops if all parity checks are satisfied.

卡尔曼滤波器算法的实现，通过对信号的追踪，描绘运动质点的轨迹，最后对算法优劣进行了误差分析，效果验证良好。(kalman filter)
