ofdm ber using matlab for qpsk

说明：  converm image to bainery

霍夫曼编码n元编码，可以计算出平均码长，编码效率(Huffman coding n-ary coding, can calculate the average code length, coding efficiency)

是一个完成循环卷积的MATLAB程序 实现方法实在时域完成的，不同于简单的频域实现，有较好的注释，一看就能懂，用的是矩阵的方法实现的(Is a cyclic convolution achieve implementation of the MATLAB program with it, the finish time domain, frequency domain is different from the simple implementation, there is a good note, one can look to understand, are used in the implementation matrix)

合成孔径雷达的点目标回波仿真MATLAB程序(Synthetic aperture radar target echo the point MATLAB simulation program)

说明：  Calling a non-local algorithm for image denoising.

this package implement a b spline algorithm in 1D 2D and 3D level. the Interpolation detail could be choose as use like.

利用拉普拉斯变换的思想，通过对数据进行差分，近似得到拉普拉斯变换后的结果，然后检查正负交换的位置，则此为极值点位置，利用此思想得到极值点的位置。(Using the ideas of Laplace transform of the data by the difference approximation get results Laplace transform, and then check the position of the positive and negative exchange, this is the extreme position, take advantage of this thinking of getting extreme points location.)

COST207信道模型，可以参考MATLAB Simulink 下也有以模块形式给出的COST207 信道模型(COST207 channel model, can refer to the MATLAB Simulink is also a module under the given COST207 channel model)

设计低通数字滤波器，要求在通带内频带低于 时，允许幅度误差在1dB以内(Design of digital low pass filter, requirements in the passband frequencies below, allow a margin of error of less than 1dB,)
