an image quality assessment trial

说明：  基于基追踪的重构图像实验，易于实现，也有相应的助手(Based on the reconstructed image based tracking experiment, easy to implement, but also the corresponding assistant)

说明：  利用压缩包内的5和函数产生PPM调制的UWB信号，信号波形为高斯二阶导函数。重复编码次数，TH码长度范围，波形形成参数alpha等参数均可以改变(use compressed within the five functions to generate PPM and the UWB signal modulation, Waveform second derivative of the Gaussian function. Repeat code number, TH code length, alpha waveform parameters such as formation parameters can be changed)
