说明：  遗传算法几个好的工具箱，给大家分享，希望互相交流(Several good genetic algorithm toolbox, to share with you the hope that mutual exchanges)

说明：  是一篇关于matlab的ofdm文章，很适合学习仿真的人(Is an article on the ofdm matlab article, it is suitable for people learning simulation)

说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

精通matlab最优化计算随书带的源码，包括线性规划，整数规划，pso，GA等(Proficient in matlab optimization calculation with the source code with the book, including linear programming, integer programming, pso, GA etc.)

一个对ADC和PLL输出结果作FFT频谱分析的matlab程序(An ADC and PLL output FFT spectrum analysis for matlab program)

这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波的OFDM，运行此程序需2分钟－3分钟的时间。 (This is a very good CP for OFDM-based maximum likelihood symbol timing synchronization and carrier synchronization of the MATLAB simulation program, after I read the absorption of classical literature in depth, repeated programming and debugging derived, code refining orderly, absolute no mistake, this process has been synchronized simulation curve is fully consistent with classical literature. Tongren have read this procedure will definitely benefit! Spared the outcome here, especially to upload to share with you friends. Tongren also welcome to provide more excellent program. Documentation required as a result of N = 1024 sub-carrier OFDM, to run this process will take 2 minutes-3 minutes.)

说明：  输入一个数判定能否开平方，能就开平方，不能就退出(Enter a few decide whether to open the square, to the open square, can not quit)

Matlab code - Cubic spline method

Converts a floating point value to IEEE 754 32 bit binary representation. Sign Bit: 1 Exp: 2 to 9 Frac: 10:32 Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used. For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following: (− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375 ​
