QPSK调制下在AWGN和Rayleigh衰落信道下的仿真以及误码率计算，包含完整的报告说明(QPSK modulation in AWGN and Rayleigh fading channel simulation, as well as bit error rate calculation, the report contains a complete description)

BIT PATTERN ANALYSIS OF COMMUNICATION SIGNALS

说明：  MATLAB 即有内建的解决很多通常遇到的曲线拟合问题的能力， 又具有附加这方面的 产品。本技术手册描述了几种拟合给定数据集的曲线的方法(MATLAB built-in solution that is often encountered in many curve fitting problems, but also has additional products in this area. This technical manual describes several data sets fit the curve of a given method)

说明：  一维FDTD的可视化实现，注释详细完备，适合初学者。光在一D真空中的传播。(The one-dimensional FDTD visualization of complete, detailed notes, suitable for beginners. That light travels in a vacuum in communication of D)

说明：  system identification continued

Linear filters process time-varying input signals to produce output signals, subject to the constraint of linearity. This results systems composed solely of components (or digital algorithms) classified as having a linear response.

The signal some times should be smoothed in planned way before submitting it to environment where now widely used algorithm is LMS

基于互信息的图像配准程序。用matlab编写的。有助于理解互信息。(based on mutual information of image registration procedures. Prepared using Matlab. Contribute to the mutual understanding of the information.)

粒子群算法用于桥式系统的可靠性优化。算法简单可靠方便。(Particle Swarm Optimization for the bridge system reliability optimization. Algorithm to facilitate a simple and reliable.)

本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)
