该算法是通过统计图像某一边缘法向方向的灰度变化情况来进行评价。即灰度变化越剧烈， 边缘越清晰， 图像也越清晰。(The algorithm is an edge of the image through the statistical method to change the direction of the gray scale to be evaluated. The more intense the gray change, the more clear the edge of the image are more clear.)

说明：  用积分方程法求P波波场，适合初学积分方程研究散射问题(Integral Equation Method P wave field)

OFDM LSE Channel Estimation； the performance of LSE channel estimation will be evaluated based on bit error rate in received data(OFDM Channel Estimation; performance of the channel estimation will LSE be evaluated based on bit error rate in received data)

惯性导航，利用惯性元件（加速度计）来测量运载体本身的加速度，经过积分和运算得到速度和位置，从而达到对运载体导航定位的目的。组成惯性导航系统的设备都安装在运载体内，工作时不依赖外界信息，也不向外界辐射能量，不易受到干扰，是一种自主式导航系统。(Inertial navigation, to measure the carrier itself acceleration Inertial element (accelerometer), through integration and operation to get the speed and position, so as to achieve the purpose of vehicle navigation. Inertial navigation systems equipment components are installed in the carriage of the body, does not rely on external information work, not to the outside world-radiation energy, less susceptible to interference, it is an autonomous navigation system.)

说明：  OFDM同步算法关于OFDM同步算法的代码，其中包括基于循环前缀的最大似然估计算法，基于训练序列的同步算法估计，以及训练序列的改进同步算法等等(The code of OFDM synchronization algorithm, including maximum likelihood estimation algorithm based on cyclic prefix, synchronization algorithm estimation based on training sequence, and improved synchronization algorithm of training sequence, etc)
