碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 95 === In recent years, the advances in the power line communication (PLC) technology have received worldwide attention, especially it can be applied to home automation, broadband network , video and audio transmission, and smart living etc. Therefore, PLC has really brought the limitless business opportunity in the competitive market of consumption. However, the power line channel can serious affects the signal transmission quality using PLC because of that the power line is not originally intended for the purpose of signal transmission. In this thesis, we use the FSK modulation technique for signal communication and evaluate the performance when OSC-ANF algorithm being applied to demodulate the received FSK signals in noisy environment. And it is achieved by software simulation. Accordingly, there are two main objects in the contents of the thesis: first of all, we use Simulink to model the equivalent circuits of the power line and the coupler, respectively, so that their frequency characteristics can meet those of real ones. Secondly, we apply the OSC-ANF algorithms to detect the signal and compare with the other method. The thesis, therefore, suggests a platform for PLC simulation, which offering a reference to different aspects as well as intention to discuss PLC.
