A simple FSK (frequency shift keying) modulation implementation in MATLAB

—The minimum variance distortionless response (MVDR) approach is very popular in array processing. It is also employed in spectral estimation where the Fourier matrix is used in the optimization process. First, we give a general form of the MVDR where any unitary matrix can be used to estimate the spectrum. Second and most importantly, we show how the MVDR method can be used to estimate the magnitude squared coherence function, which is very useful in so many applications but so few methods exist to estimate it. Simulations show that our algorithm givesmuchmore reliable results than the one based on the popular Welch’s method.

对图像进行非下采样小波变换，得到一个低频子带和若干个高频子带。(Under the image of non-sampling wavelet transform, to get a low-frequency sub-band and a number of high-frequency sub-band.)

粒子群算法 Matlab编程实现 这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。 (Particle swarm algorithm Matlab programming, this program is the basic particle swarm optimization algorithm procedures, using Matlab, very simple. Only a few dozen lines of code.)

室内环境射线跟踪算法研究，室内反射点追踪的计算(Indoor environmental ray tracing algorithm to calculate the reflection point indoor track)

依次输入exchange swap tianchongJ即可，若想修改全排列矩阵的大小，可在MATLAB中打开tianchongJ修改J和N。 (Enter exchange swap tianchongJ in turn can, If you want to modify the full array matrix size can be modified in MATLAB to open tianchongJ J and N.)
