基于matlab的关于遗传算法的一些重要的函数的m文件，供读者参考 (Based on some of the important matlab m file on genetic algorithm function for readers reference)

FIR滤波器， 设计一个线性相位有限冲激响应低通滤波器，使其满足如下指标：通带边界为2kHz，阻带边界为2.5kHz，通带波纹 =0.005，阻带波纹 =0.005，抽样率为10kHz。采用多尔夫-切比雪夫窗进行设计，进行频谱分析。(FIR filter, design a linear phase FIR low-pass filter to meet the following indicators: passband border to 2kHz, stopband border to 2.5kHz, passband ripple = 0.005, stop-band ripple = 0.005, sampling rate of 10kHz. Used Dorf- Chebyshev window design, spectral analysis.)

医学图像经典预处理，matlab文件，可直接编译(Classic pre-medical images, matlab file)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

利用MATLAB 仿真工具设计出一个QPSK仿真程序，以衡量QPSK在理想信道、高斯白噪声信道和先通过瑞利衰落信道再通过高斯信道三种方式的调制解调得到的功率谱密度、噪声曲线、星座图及误码性能,并对仿真结果进行了分析。(QPSK simulation design and Realization Based on MATLAB)
