PLL的simulink仿真模型，希望能有用，谢谢大家(PLL in simulink simulation models, hoping to be useful, thank you)

is-95和2000的 前向链路仿真 源程序 发射机和 信道 及接收机的完整程序。另有复杂信道的源程序 可以联系 索取。(is a complete program of-95 and 2000, the first to link simulation source transmitter, channel and receiver. Another source of complex channel can be obtained by contacting.)

— In ultra-wideband (UWB) indoor dense multi-path transmission environments, traditional coherent Rake receiver requires estimation of channel parameters. Moreover, in order to collect enough signal energy from dense multi-path components, the number of Rake fingers must be large enough. Consequently, the receiver structure is too complex to be implemented in practice.

能够非常有效地在比较大的干扰下比较准确地反映真实值，如果观测端加入干扰较大时，卡尔曼滤波器能够较为有效地进行滤波，不过当状态端的干扰增大时，卡尔曼滤波器的滤波效果也会随之下降。(Can very effectively in the relatively large disturbances under more accurately reflect the true value, if the observation end joining interference is large, Calman filter can effectively filter, but when increasing the jamming state end when the filter effect of Calman filters will fall.)

本程序采用MATLAB编写，内容关系数字图形分析与处理，内有例子说明使用(This program written by MATLAB, the contents of relations figures graphical analysis and processing, there are examples of the use)

旋转矩阵和四原数之间的转换 用于坐标系之间的相互转换(Rotation matrix and the number of conversions between the original four)

标准的图象配准MATLAB程序，效果不错！(Standard MATLAB image registration procedures, good results!)
