programming for Omni-directional image. they are useful for novice.

一个参照葛德彪书编写的3D FDTD源文件，用matlab语言编写，非常详细的注释，很易看懂,2mur bianjie(GE De-biao a reference book, prepared by 3D FDTD source files, using matlab language, very detailed notes, it is easy to understand, 2mur bianjie)

Poisson equation solver

3、 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与(1)的曲线进行对比。 (3, the Rayleigh channel modulation and demodulation, channel estimation: (1) Please derive the single-path Rayleigh channel coherent demodulation of BPSK BER performance theory, and draw the signal to noise ratio and bit error rate curves. (2) single-path Rayleigh channel, please design a division of the guide-assisted channel estimation method, using Simulink simulation, measurement of the BER performance of BPSK, draw-bit signal to noise ratio and bit error rate curve, and with (1) of the curves were compared. )

for some reason the last part is id, which i don t want and the parts seem to be in the reverse order the one in which we find the data itself.

说明：  lms自适应均衡的MATLAB仿真程序，适合通信信号处理初学者(lms adaptive equalization of the MATLAB simulation program for communications signal processing for beginners)

最小生成树prim算法，Dandn文件给出了输入参数的名称及格式即在调用prim前先输入邻接矩阵D和节点个数n输入prim得到两行的矩阵T,将上下两行数字对应的节点相连即可(Prim algorithm for minimum spanning tree, Dandn document gives the name and format of the input parameters that is called prim before Input adjacency matrix D and the node number n input prim to be two lines of the matrix T, the upper and lower figures correspond to two lines of nodes connected to can)

it is for designing filter
