deltamodulation

Matlab code for simulation of radar received power versus range. There are other files for additional features like aperture area, swirling objects and pulse integration Happy learning!

国外Lupash Consulting公司开发的GPS工具箱，内有详细的使用手册，功能全面强大。非常好用(Lupash Consulting abroad GPS kit developed with a detailed user manual, full-featured powerful. Very good)

共轭梯度法是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。(Conjugate gradient method is between the steepest descent method and Newton method between a method that only use the first derivative information, but the steepest descent method to overcome the disadvantage of slow convergence, but also avoids the need to store and calculate Newton Hesse matrix and the shortcomings of the inverse, conjugate gradient method is not only linear equations to solve large-scale one of the most useful, large-scale nonlinear optimization solution is also the most efficient algorithms.)

说明：  generate white noise

说明：  编好的两阶段启发式算法求解LRP问题，里面嵌套节约算法(Two-phrase heuristic algorithm LRP)

This estimator correctly identifies the two distinct directions of arrival.

使用混沌与分形分析的例程，包括面积、周长、矩形度、伸长度，主要为数据分析和统计，PLS部分最小二乘工具箱,matlab程序运行时导入数据文件作为输入参数，针对EMD方法的不足。( Use Chaos and fractal analysis routines, Including the area, perimeter, rectangular, elongation, Mainly for data analysis and statistics, PLS PLS toolbox, Import data files as input parameters matlab program is running, For lack of EMD.)

自己写的广义LDPC的程序，包括编译码，其中最重要的是一码算法，用的是chase算法，有很好的性能，希望可以跟大家交流改进(Generalized LDPC write procedures, including the encoding and decoding, most important of which is a code algorithm, using a chase algorithm has good performance, hoping to improve communication with everyone)
