小波阈值去噪的源代码.不同的阈值函数可以修改阈值函数.从而实现功能.(wavelet thresholding source. Different threshold function can change the threshold function. Thus achieving functional.)

对最优波束形成准则中的最大信噪比，给出了其Matlab仿真源程序程序。(The optimal beamforming standards to the maximum signal-to-noise ratio, and gives the Matlab source program. )

由于传感器自身以及通信延迟等原因, 使得异步多传感器数据融合问题比同步问题的研究更 切合实际。 对连续时间系统在融合中心和各传感器节点分别进行异步离散化处理,离散后过程噪声与测 量噪声以及测量噪声之间相关,虽然相应连续时间系统中的噪声是不相关的。 最后推导了相关噪声情况 下的异步融合算法,仿真结果说明了算法的有效性。(Due to t he r easons of senso rs in it self and the communication delays, the r esearch of t he asy nchr onous multisensor da ta fusion pr oblem is mo re pr actical than t hat o f synchro no us one. Firstly t he continuo us-time system is discr etig ed in the fusio n center and all t he senso r nodes w it h differ ent sample interv al.
