简单SENSE图像重建，即使通过反傅里叶变换重建出最终图像(The data was acquired from 4-channel array coil using EPI sequence (2-shot, matrix: 64X64, TE: 50 ms) at a 1.5T scanner. The code estimates the coil sensitivity profiles directly from the image with anatomical contrast by low-pass smoothing. Subsequently, k-space data were decimated to simulate 2.0-fold acceleration (R=2.0). Finally, using least-squares estimate, the reconstructed full-FOV spin density image is obtained)

通过应用于小波变换到lena.jpg图像，简单实现图像压缩，实现一级压缩和二级压缩(Through applied wavelet transform to lena.jpg image, a simple image compression, compression and two compression to achieve a)

it includes normalizatiom filters in speech and some other codes

基于最大信干噪比准则的自适应数字波束形成器程序(Based on the maximum SINR criteria for adaptive digital beamformer program)

说明：  阵列信号波达方向的估计，程序运行是成功的。(DOA estimates)

应用matlab求极值和求根的方法，并配有仿真程序和结果，可以用于数值实验时使用(Application matlab extremum and rooting, and with a simulation program and results can be used for numerical experiments)

基于matlab的关于遗传算法的一些重要的函数的m文件，供读者参考 (Based on some of the important matlab m file on genetic algorithm function for readers reference)

频数统计，能够统计变量的出现的频数，还比较好用。(Frequency statistics, the statistical variables appear frequency, but also relatively easy to use.)

SBOGA 用顺序选择遗传算法求解一维无约束优化问题 (SBOGA order to select genetic algorithm for solving one-dimensional unconstrained optimization problems)

matlab是集数学计算、图形处理和程序语言设计于一体的软件，通过matlab来实现数字信号处理的有关表达，最终实现课程设计的目的。(matlab is a mathematical calculation, graphics processing and programming language design software integrated through matlab to realize the digital signal processing of expression, and ultimately realize the purpose of curriculum design.)
