gram schmidt algorithm to compensate i and q channel imbalance in noisy channel

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

说明：  小波神经网络实例，用一周的数据来预测未来一天的情况，使用MATLAB软件实现人工智能的方法。(A wavelet neural network example is used to predict the situation of the next day with one week's data. MATLAB software is used)

In this program we calculate the scattering field of a infinite rectangular surface. I use Physical Optic method and compare the result with exact solution.

gcc and gnu compilers

The program uses a simple algorithm to calculate the deflection at each point of a cantilever beam subjected to arbitrary loading distribution, the program also calculates and plots the bending moment and shear force in the beam.

： 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理， 重点研究了理想同步情 况下， 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系 统模型的基础上， 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下， 保 护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线， 得出了较理想的结论。 关键词： 正交频分复用； 仿真； 循环前缀； 信道估计(good)
