matlab环境下的低通滤波设计及实现，我也不是很懂(matlab environment of low-pass filter design and realize, I do not很懂)

this program transfer geodetic coordinates to UTM. it is simple but good work.

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

通过卫星的测量方程和状态方程来求解卫星的姿态。包括四元数，角度，角速度等等。(By satellite measurements to solve equations and state equations of satellite attitude. Including the quaternion, angle, angular velocity and so on.)

SIMMM1 simulate a M/M/1 queueing system. Poisson arrivals of intensity lambda. Poisson service times S of intensity mu.

This program is a new way to estimate the coherence function. It s based on the MVDR and is much more reliable than the classical Welch s method implemented in MATLAB. There are 2 programs: the main program called coherence_MVDR.m and and an example, called illustrate.m, that calls the main function to show how it works. There also included 2 papers that we published on this algorithm. (This program is a new way to estimate the coherence function.
