Wireless sensor network mac protocols.Its explanations...and implementations

sound very useful e-book

this is main program of tomography modelling

这是利用一个simulink环境下简单得PPT文件，希望对大家有帮助，谢谢！(This is the use of a simple simulink environment have PPT file, we want to help, thank you!)

Fuzzy clustering methods including subtractive and Fuzzy C-means and comparing them to Kmeans clustering method

Simulation of DOA estimation using MUSIC alg

采用Matlab编写的有限元方法，效果非常好(prepared by the Matlab finite element method, the effect was very good)

该Matlab.m文件，产生BPSK调制信号，连带解调过程实现(This is a matlab .m file.It is used to generated BPSK signal and the demodulated signal too.)

根据干扰信号波形样式的不同，压制性干扰可分为噪声调幅干扰、噪声调频干扰、噪声调相干扰。就是用噪声或类似噪声的干扰信号遮盖或淹没有用信号，阻止雷达检测目标信息。它的基本原理是：任何一部雷达都有外部噪声和内部噪声，雷达对目标的检测是在这些噪声中进行的，其检测又是基于一定的概率准则的。一般来说，如果目标信号能量S与噪声能量N相比（信噪比S/N），超过检测门限D，则可以保证一定的虚警概率Pfa的条件下达到可检测目标回波所要求的检测概率Pd，简称为可发现目标，否则便称为不可发现目标。(Blanket Jamming can be divided into different styles according to the interference signal waveform, noise AM interference, noise FM jamming noise phase modulation interference. With noise or noise-like interference signal covered or submerged useful signal prevent radar detection target information from. Its basic principle is: any one radar has the external noise and the internal noise of the radar target detection in these noise detection is based on a certain probability criterion. Generally, compared to if the target signal energy S and noise energy N (signal-to-noise ratio S/N), more than the detection threshold D, you can guarantee reach target echo can be detected under the conditions of a certain false alarm probability Pfa requirements detection probability Pd, referred to can be found in the target, otherwise known as not finding the target.)

这个是机械领域的二级展开圆柱斜齿减速器 设计的一些计算程序 自动化不高 要根据情况 改一些数据 但程序里有详细的说明 高手可以把它用GUI实现了(This is the area of secondary mechanical start helical gear reducer design automation of some of the computer program does not change according to the situation Gaoyao some data but the program in detail as master, it can be achieved with a GUI)
