ofdm ber using matlab for qpsk

对于飞控系统的设计非常重要，是半实物仿真的必备工具，从事无人直升机的必须品(For the flight control system design is very important and is an essential tool for loop simulation, in the necessities of unmanned helicopter)

Matlab编写的仿射变换程序，有两个，都不错(Affine transformation program written in Matlab, there are two, are good)

说明：  通过MATLAB源码可以设计多种分数阶延时滤波器。(methods to design fractional delay filter)

说明：  平行射线滤波反投影，算法简单，通过对投影滤波后，重建的图像效果好。(Parallel rays filtered back projection algorithm is simple, by filtering the projection, the reconstruction of the image effects.)

对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)

说明：  利用IMU的加速度和陀螺仪数据进行轨迹估计(Trajectory estimation using the IMU data)

利用MATLAB模拟的细胞自动机程序，可以借用来研究怎么写此类程序(Using MATLAB simulation of cellular automata program, you can borrow to study how to write such programs)

小波变换的Matlab程序源代码，除了小波图像压缩算法外，还包括图像重构函数。(Wavelet Transform Matlab program source code, apart from wavelet image compression algorithm, also includes the functions of image reconstruction.)
