This is an archive for background remove images.

地震数据处理软件包，包括f-x预测滤波等，非常实用，搞地震方面的可以参考 (Seismic data processing software, very useful, engaging earthquakes can refer to )

粒子群算法，可以自己确定惯性系数的函数式，扩展性良好，可以实现多维(Particle Swarm Algorithm)

说明：  计算给定矩阵的互信息，这时的相关性是利用互信息来判断，矩阵的形式为邻接矩阵(compute the mutual information of the given matrix such as the matrix the elements in it are 0 or 1.)

To understand the traffic mechanism and find optimal strategies to improve traffic capacity is one of the important issues we have to address.

the above function is useful to find the derivative of a bspline

对一维噪声信号进行信号处理，设计软阈值去噪、硬阈值去噪、以及多种阈值规则(to solve some problems)

由Matlab进行数据处理，向DSP传递图像数据，再由DSP反馈处理后的数据，发挥两者优势，从而快速评估图像质量(From the Matlab data processing, transfer the image data to the DSP, and then processed by the DSP feedback data, play two advantages to quickly assess the image quality)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
