直接型IIR滤波器实现源代码，希望与大家共同分享！(Direct IIR filter source code, I hope to share with you!)

用matlab分析bPSK和qpsk的误码率，其中有psk信号的调制与解调(psk)

基于蒙特卡罗法2PSK系统抗噪声性能仿真 编写MATLAB的M文件，用该文件的采用相干解调法的2PSK系统的抗噪性能进行1000个符号的蒙特卡罗法仿真，画出误码率与信噪比之间的关系曲线(Based on the Monte Carlo simulation of anti noise performance of 2PSK system Write a MATLAB M file, the file by using the coherent demodulation method for 2PSK system anti-noise performance of 1000 symbols of the Monte Carlo simulation, draw the error rate and signal to noise ratio and the relation curve between the )

程序包里面包含了，NFSK，NPSK，16QAM调制信号的产生函数，以后大家编程时也能用到 后面还有调制识别的程序，相当完整。 (Package which includes, NFSK, NPSK, 16QAM modulation signal generation function, after all programming can be used to back when there is modulation recognition procedure, quite complete.)

运用平面波展开法模拟光子晶体光纤中的带隙结构(The use of plane wave expansion method in photonic crystal fiber simulation of the band structures of)

用MATLAB实现图像的离散余弦变换，程序运行结果表明离散余弦变换能够起到压缩图像的目的。(in order to compress the bite of pictur,the program use the DCT to compress.)

说明：  Matlab下的遗传算法程序，还可以，比较详细。 大家自己(genetic algorithm, but also, more detailed. We all try)

说明：  matlab编写，贝叶斯估计程序，简单易懂。(Matlab prepared, Bayesian estimation procedures, simple and understandable.)

递推最小二乘程序，是进行系统辨识很好的程序(Recursive least-squares procedure, is a good program for system identification)

合成孔径雷达中经过滤波器的线性调频信号的仿真 与未经过滤波器的线性调频信号不同 具有很好的参考价值(The simulation of synthetic aperture radar chirp signal filter and the filter has not been different chirp signal has a good reference value)
