说明：  用小波和小波包对太阳黑子数据进行降噪处理(Using wavelet and wavelet packet noise reduction processing on the sunspot data)

matcad.it is about the use of mathcad very usefullA!!

通信学中的QAM调制，这是一个比较经典的程序(QAM in communications )

this mablat is going to find out the max SIR and min SIR on wireless communication

说明：  这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模块，并统括系统性能的仿真验证了系统设计的可靠性。(This is a relatively complete simulation of OFDM communication system design, including coding, modulation, IFFT, and down conversion, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding module, and system performance omnibus simulation of the system reliability.)

实现了通信中的MATLAB的最大似然译码操作(implement the ml method in the communication system)

G-P算法计算关联维数，可以运用在混沌时间序列的瓦斯浓度预测研究中(GP algorithm to calculate the correlation dimension, you can use the gas concentration in the prediction of chaotic time series in)

GammaMap滤波器函数，很好用，MATLAB语言。(GammaMap filter function, useful, MATLAB language.)

t - time series y - value of series at time t w - cycle length, defined by user based on prior knowledge of time series alpha - type I error used for cofidence interval calculations. Usually set to be 0.05 which corresponds with 95 cofidence intervals(t- time series y- value of series at time t w- cycle length, defined by user based on prior knowledge of time series alpha- type I error used for cofidence interval calculations. Usually set to be 0.05 which corresponds with 95 cofidence intervals)

通信工程中m序列编码，自相关，互相关计算,组合码的产生,GOLD码的产生(Communication Engineering in m-sequences encoding autocorrelation, cross-correlation calculations, produce a combined code, GOLD code generation)
