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： 简单遗传算法MATLAB实现，详细的介绍了简单遗传算法的实现过程，并以一个简单的函数优化作为案例说明了其应用。但是由于该测试函数过于简单，在实际的应用过程中，还需要对相关参数进行调整，使其效率得到更大的提高。(Simple genetic algorithm based on MATLAB realize, describes in detail the process of simple genetic algorithm, and a simple function optimization as a case illustrate its application. However, since the test function is too simple, in the actual application process, the relevant parameters need to be adjusted to greater increase efficiency.)
