摘　要:根据HFC网络上行信道的特性,建立了信道模型 分析了上行信道中存在的各种噪声对QPSK 调制技术的影响。结果表明在C /N (传输信道载噪比)较低的情况下,采用QPSK调制方式,可以提高系 统的抗干扰能力。 关键词: QPSK 光纤同轴电缆混合网 上行信道 噪声(Abstract: HFC network in accordance with the characteristics of the uplink channel, the establishment of a channel model an analysis of the various uplink channel noise on the impact of QPSK modulation. The results show that the C/N (transmission channel carrier-to-noise ratio) lower, the use of QPSK modulation, can improve the system of anti-interference ability. Keywords: QPSK hybrid fiber coaxial cable network uplink channel noise)

说明：  杂波的一个MATLAB仿真，杂波的产生：先生成一个（0，1）分布的随机数r，让后根据poission分布产生杂波的个数n，这n个杂波是服从均匀分布(Clutter a MATLAB simulation, the resulting clutter: a President (0,1) distribution of the random number r, let poission distributed according to the number of clutter have n, that n is subject to a uniformly distributed clutter)

it can be used for neural network

dynamic mfile for power systems stability (3 machine)

harris角点检测，并对检测的角点用NCC进行匹配(harris corner detection, and detection of the corner points are matched with NCC)

说明：  基本遗传算法maltab源程序， 比较实用(Maltab basic genetic algorithm source code, more practical)
