研究多进制脉冲位置调制和关闭键控在直接检测光无线通信系统中存在的大气影响，比较了ook与PPM调制方式的区别。(M-ary pulse position modulation on and off keying atmospheric effects in the direct detection of optical wireless communication systems, compare the difference of the ook PPM modulation mode.)

设计一CQMFB，低通滤波器H0(z)来自一半带滤波器。该半带滤波器的长度为47，通带截至频率ωp = 0.42π，试给出H0 (z)，H1(z)，G0(z)，G1(z)的幅频响应，单位抽样响应并画图。(Design a CQMFB, low-pass filter H0 (z) the half-band filter. The length of the half-band filter 47, the passband cutoff frequency ωp = 0.42π, try to give H0 (z), H1 (z), G0 (z), G1 (z) of the amplitude-frequency response, the unit sample response and Paint.)

奇异值分解及欧式距离计算，两组数据之间的计算(singular and calculate distense)

face recognition with R and C matrix. get a picture from a defined path and construct the R and C matrix and find the points that are related to the face part of the given picture

说明：  利用FFT对原信号进行变换，然后在频域进行处理，再使用IFFT进行反变换，达到滤波的目的。(use FFT and IFFT to filter)
