Cancelamento de ruido acustico

用MATLAB编程出自适应时域均衡在均衡前与均衡后的眼图对比（低通信道和多径信道），还有误差曲线(Programming with MATLAB the adaptive time-domain equalizer in the balance before the balance of the eye diagram after the contrast (low communication channel and multi-path channel), as well as the error curve)

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))

模糊k均值算法，将模糊理论和k均值聚类算法想结合。(fuzzykmeans clustering ,combine the fuzzy theoy and kmeans clustering.)

在：1）理想无噪生条件，2）SNR=10dB，3）SNR=20dB，4）两径衰落信 道{0, 0}、{-6dB，-10symbol}条件下，分别产生 1000 个符号的 QPSK、8PSK、 16QAM 星座点， 画出信号序列的星座图， 提交电子版信号产生、 加噪、 显示的*.m 程序和电子版 WORD 报告。 报告要求给出原理描述、 框图和分析说明输出结果。(In: 1) an ideal noiseless Health conditions, 2) SNR = 10dB, 3) SNR = 20dB, 4) two-path fading channel {0, 0}, {-6dB,-10symbol} under conditions generate 1,000 symbols QPSK, 8PSK, 16QAM constellation points, draw constellation signal sequence, submit an electronic version of the signal, noise, display*. m procedures and electronic WORD report. Reporting requirements given Principles, and the analysis shows a block diagram of the output.)

matlab中的数据插值描述，和大家一起分享参考(Matlab interpolation of data description, and others together to share information)

it use to extract thre feature of ecg signal using pca

this gives you detailed abt the active power filter and its used. You can mitigates the harmonics by using a active power filter.

说明：  对地震波进行数值模拟，设置不同波速的分界面模拟地震波传播(Seismic wave numerical simulation under different wave velocities)

说明：  cbf，mvdr等波束形成仿真程序，最终达到精确定位的效果(cbf,mvdr,Beamforming technology,The simulation program,To achieve the effect of positioning.)
