Matlab语言中常用的算法程序集，包含了如数值微分， 解线性方程组的迭代法等等方法，便于你学习Matlab(Matlab language commonly used algorithm assembly includes, such as numerical differentiation, solution of linear equations of the iteration method, etc., to facilitate you to learn Matlab)

这个程序在认知无线电中的频谱计算方法，是一种经典的计算方法，十分好用。(The program in cognitive radio spectrum is obtained by a classical method of calculation is very easy to use.)

聚类的测试数据集，matlab打开，3个cluster，1W个测试点，2维。(clustering test data sets, Matlab open, 3 cluster, 1W tests, the two-dimensional.)

Fibonacci method is an optimization method which can be used to find optimum of a 1D function (even discrete function) using elimination method. For use this method the initial interval of uncertainty, in which the optimum lies, has to be known. In addition the objective function should be unimodal, which has just an optimum solution in initial interval.

利用matlab的m文件，仿真DPSK的差分相干解调法，从发送数据到接收数据，比较完整(Use matlab m files, simulation DPSK differential coherent demodulation method to send data to receive data from a relatively complete)

实现了图像的灰度化并进一步用于视频监视控，利用matlab GUI实现的串口编程例子，分析了该信号的时域、频域、倒谱，循环谱等。( Achieve a grayscale image and further control for video surveillance, Use serial programming examples matlab GUI implementation, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc.)

A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the proposed method employs a two stage estimator, which greatly minimize the computational complexity.
