Personal Communications Services (PCS) require low-power radio technologies. One such transceiver architecture employing frequency-hopped spread spectrum techniques is described. Low power and robustness are two keys to a wireless personal communications device.

学习matlab的ppt课件（华中科技大学的内部资料）(Ppt of learning courseware matlab (Huazhong University of Science and Technology)

Spectral density, FFT, PSD,

matlab 模糊工具箱函数，包含了大部分的模糊工具箱函数，很实用(Matlab toolbox functions, including most of the fuzzy toolbox function, practical)

matlab进行小波分析，调用matlab内部函数进行M文件编程(MATLAB wavelet analysis, call the internal function matlab M-file programming)

说明：  平行射线滤波反投影，算法简单，通过对投影滤波后，重建的图像效果好。(Parallel rays filtered back projection algorithm is simple, by filtering the projection, the reconstruction of the image effects.)

伪随机序列PRBS（M序列）的产生文件，matlab 语言开发，适合于系统辨识的激励信号(Pseudo-random sequence PRBS (M series) and generate the file, matlab language development, incentives for system identification signal)

数字相控阵雷达幅度和差子函数和相位和差子函数，基于理想去斜信号回波仿真(Digital phased array radar amplitude and differential sub-functions and phase and differential sub-functions, based on the ideal ramp signal echo simulation)

Modified Gram-Schmidt (MGS)正交化法是利用已有正交基计算新的正交基。既能选择相关特征，又能排出已选特征对后续特征选择的影响。(Modified Gram-Schmidt (MGS)orthogonalization gives new orthogonal basis through original orthogonal basis. It can do the feature selection and eliminate the impact on choosing new feature vector by the selected one.)
