这是一个关于BPSK在高斯信道的仿真程序，仿真最后给出BPSK在高斯信道的信噪比 误码率曲线(This is a BPSK in Gaussian channel on the simulation, emulation BPSK given the signal to noise ratio in Gaussian channel bit error rate curve)

信道编码和无线电技术的一些MATLAB源代码(MATLAB source code of the channel coding and radio technology)

在实际计算中，有时为了避免开方运算，或者要分解的矩阵只是对称而不是正定的，这时可以选用适合于一般对称阵的分解式(In the actual calculation, sometimes in order to avoid root operation, or just want to break down the matrix rather than positive definite symmetric, then you can choose suitable for general symmetric matrix factorization)

采用最小二乘法，对水位数据进行调和分析。可同时处理多个站点的水位调和分析，站点个数不限，在输入文件中可更改分潮个数。(Least squares method, the water level data for harmonic analysis. Can simultaneously handle multiple sites water harmonic analysis, number of sites not limited to, change in the input file, the number of sub-tidal.)

BP神经网络的非线性系统建模-非线性函数拟合，数学建模常用(BP neural network nonlinear system modeling- the non-linear function fitting, commonly used mathematical modeling)

介绍了其中处理EMD端点效应的方法，还有其中两种改进算法的程序，适合EMD的学者。(Introduces seven kinds of processing methods of endpoint effect the EMD, and one of the two kinds of improved algorithm procedures, suitable for scholars of the EMD.)

该算法构造了一个列重为4的校验矩阵，并检验了是否存在周长为8的环(The algorithm constructs a series of important check matrix of 4 and test whether there was a perimeter ring of 8 )
