Matrix techniques for modelling ultrasonic waves in multilayered media。This paper presents a review of the main developments of the matrix techniques, and their use in response and modal models, with emphasis on ultrasonics applications(Matrix techniques for modelling ultrasonic waves in multilayered media)

用于接收机的载波同步，利用锁相环实现解调，用于相干解调(Carrier for receiver synchronization, phase-locked loop to achieve demodulation for coherent demodulation)

岩石物理模型建模的另一种方法，同样可以翻译弹性参数与物性参数间的关系。(Another method of rock physics modeling, the same can translation parameters and physical parameters of elastic)

说明：  鲸鱼优化算法(WOA)也是一种元启发式优化算法。一种新的模拟座头鲸狩猎行为的元启发式优化算法(鲸鱼优化算法，WOA)。目前的工作与其他群优化算法相比的主要区别在于，采用随机或最佳搜索代理来模拟捕猎行为，并使用螺旋来模拟座头鲸的泡泡网攻击机制。(Whale optimization algorithm (WOA) is also a meta heuristic optimization algorithm. A new meta heuristic optimization algorithm (whale optimization algorithm, WOA) is proposed to simulate the hunting behavior of humpback whales. The main difference between the current work and other swarm optimization algorithms is that the random or optimal search agent is used to simulate the hunting behavior, and the spiral is used to simulate the bubble net attack mechanism of humpback whales)

计算CDMA系统的误码率的最重要的函数，记得看哦，肯定有用(The most important function to calculate the error rate of the CDMA system, remember Kane, certainly useful)

当前工程上广泛采用了一种高效滤波器，即CIC（cascaded integrator-comb filter）将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)

说明：  hi image denoising.......it works like a charm

特征提取代码，提取pca_sift特征，用于图像特征提取，图像配准或匹配，可供做这方面研究的同学参考。(feature extraction image matching)

这个是关于MSK调制的MATLAB仿真程序，对正在研究MATLAB调制信号的人来说很有用，其中含有仿真图。(The MSK modulation MATLAB simulation program, useful to the people being studied MATLAB modulation signal, which contains the simulation Fig.)

这是个MATLAB 得程序，有关的内容是 无线传感器网络得拓扑控制问题，一共有1个算法，希望对对无线传感器网络感兴趣的得大大们有一定的帮助。谢谢大家。 (it is the problem of topology control, if you are interested in it please download it . )
