用汉宁窗函数法设计一个数字FIR高通滤波器，要求通带边界频率为500Hz，阻带边界频率为400Hz，通带最大衰减1dB，阻带最小衰减40dB，抽样频率为2000Hz，用MATLAB画出幅频特性，画出并分析滤波器传输函数的零极点(With han ning window function method to design a digital FIR high-pass filter, request bandpass boundary frequency for 500 Hz, stop-band boundary frequency for 400 Hz, bandpass biggest 1 dB attenuation, stop-band attenuation least 40 dB, sampling frequency for 2000 Hz, MATLAB draw the amplitude frequency characteristics, painted and analysis filter transmission function of zero poles)

金融数据分析的一个新的程序码 可应用于数据分析 价格以及期货指数估计 还可用于 几何布朗运动的模拟("An estimation technique for Time Indexed gaussian Mixture Models", we propose a model specification that can be used to describe data with spikes, jumps, mean reversion, geometric brownian motion, you name it... We then develop an estimation procedures to extract the parameters from data generated from this model. The original intent was to develop a model for electricity price spike, however it can be extended far beyond this. A more general extension of this basic idea using particle filtering is developed in another paper.)

比较采用干扰消除和无干扰消除的V-BLAST系统误帧率与SNR的关系曲线。系统参数：收发天线个数M=4，N=6；设定发送信号总功率P=1；设定每一帧中的符号数Nframe=100；调制方式为16QAM；信道为不相关瑞利衰落信道。(Was used to compare the interference canceller and V-BLAST system without interference cancellation, the frame error rate and SNR curve. System parameters: the number of transmit and receive antennas M = 4, N = 6 set to send the signal power P = 1 set the number of symbols in each frame Nframe = 100 modulation for 16QAM channel is not related to Rayleigh fading channel.)
