来自长江水质评价与预测全国得奖论文的源代码，仅供大家参考学习(From the Yangtze River water quality assessment and prediction of the award-winning paper source code, for your reference learning)

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)

卡尔曼滤波 可以对目标进行跟踪，数据处理 滤波(Kalman filter can track the target, data processing filter)
