PQevalAudio :Perceptual Evaluation of Audio Quality

WT，c++写的，还不是我写的，就是一个教学资料，开通账户用的(WT, written by c++, not written by me, is a teaching material for opening an account)

说明：  基于同步回代法的场景缩减程序，已调试成功，可直接使用。(The scenario reduction program based on simultaneous backward reduction method has been debugged successfully and can be used directly.)

机动目标的跟踪问题一直是人们研究的重点，实现机动目标精确跟踪，首要解决的问题就是使所建立的目标运动模型与实际的目标运动模型匹配。目前常用的有多模型(MM)，交互式多模型(IMM)，切换模型等。多模型方法就是对一组具有不同机动模型分别进行Kalman滤波，最终的参数估计是各滤波器估计值的加权和；在多模型基础上，Shalom提出了交互式多模型方法，这一方法对无序目标的机动检测，显示了更好的鲁棒性和跟踪的稳定性；切换模型则是分别建立机动和非机动运动模型，利用机动检测实现在这两个模型之间的切换。一般来说，交互式多模型的跟踪性能较好。-mobile target tracking problem has been a focus of research and achieve precise maneuvering target tracking, the most pressing issue is to enable the establishment of the target model and the actual movement of the target model matching. At present, more commonly used model (MM), interactive multi-model (IMM), switching model. Multi-model approach is a group of different mobile models were Kalman filtering, The final parameter is the estimated value of the filter is estimated weighted; in the multi-model basis, Shalom made the interactive multi-model approach that the objectives of the motor disorder detection, better show the robustness and stability of the track; switching model is set up motorized and non-motorized sports

使用JAVA制作的局域网聊天程序_JBuilder开发的Java聊天程序，支持聊天头像，支持功能设置、断线、离线、在线等状态更改，当时是一个JAVA作业，看来完成的相当不错哦。

利用ewb 实现的混频电路-Ewb realize the use of the mixer circuit

对于有尖峰的非高斯海杂波，有几种模型来进行拟合，比较流行的有对数正态分布、韦布尔分布和 K 分布等。该程序通过改进实测数据海杂波拟合PDF分布(Sea clutter fitting PDF distribution by improving measured data)
