active_filter_demo

a new algorithm for computing sparse signal representations using overcomplete dictionaries

国外编写的一个QPSK仿真程序，给出了调制解调及误码分析(Foreign QPSK simulation program written in a given modulation and demodulation and error analysis)

主要是基于extreme learning machine的改进算法，结合了增量学习(It’s mainly based on the extreme learning machine improvement algorithm, unified the increase study )

利用matlab自己建立光栅，别且进行方向滤波，效果十分明显(Grating using matlab to establish their own, do not and the direction of filtering, the effect is very obvious)

simulation the converter DC to DC single phase command with process of implosion

室内定位时差定位算法。包括 chan算法，fang算法。功能是实现室内定位。在3到7个接收基站的基础上，获得较高精度的定位(Indoor location TDOA location algorithm. Including Chan algorithm and Fang algorithm. Function is to achieve indoor positioning. On the basis of 3 to 7 receiving base stations, high precision positioning can be achieved.)

说明：  通过16个接收水听器组成线列阵，分别给出各个阵元接收信号，可实现 时域、频域等信号到达角判别(A linear array composed of 16 receiving hydrophones can be used to distinguish the angle of arrival of signals.)

LDPC码在MATLAB中的八环成功仿真算法，大围长QC-LDPC码。值得学习一下(LDPC code in MATLAB in the eight-ring successful simulation algorithm, large-scale long QC-LDPC code. Worth learning)

此MATLAB程序实现函数的阶乘功能，经调试，完全正确(Procedures for implementation of this MATLAB function factorial function, with debug, completely correct)

数理应用统计中，对非中心塌方分布的参数进行估计(parameters estimated on the distribution of non-center collapse)
