【摘要】 随着INTERNET的发展和宽带城域网及数据网的全面建设，家庭数据网络将是下一个数据化目标。因而导致最后一公里甚或最后一公尺的数据传输的瓶颈由于技术的成熟、市场的需求的驱动将被打破。目前有多种技术解决这一问题。利用现有资源的技术有DSL技术、HomePNA技术、电力线通信技术和CABLE MODEM技术。 利用原有电力线路传送数据，以达到对用电设备进行监测、控制的目的，是一件非常有意义的事情。因为这样做可以充分利用现有的无处不在的电力网资源，使系统建设大幅度降低成本，快捷便利，且通达千家万户。本文针对利用电力线传输数据时所遇到的噪声干扰和严重的线路衰减问题，分析如何克服这些干扰、衰减，保证数字信号在电力线准确传输，介绍扩频技术、纠错技术、DSP技术、Lonworks总线技术等在电力线载波系统中的应用。另外，本文还提出了一个电力线载波收发器在软、硬件上的实现模型。更多还原

【Abstract】 With the development of INTERNET and the rapid construction of wide-band MAN, residential network has become one of the hotspots of research and investment. The limit which caused by low data transmission speed in the last kilometer of transmission line has been overcome by the advancement of corresponding skill and prompt of market requirement. Now there are several available technology we can choose to solve the problem. For example, DSL, HOMEPNA, COMMUNICATION OVER EXSITING AC MAIN WIRING , CABLE MODEM, all technologies mentioned above take advantage of exsiting resource.It’s significative to communicate over existing AC main wiring in order to control and monitor electric appliance. By this way, we can make full use of power line network which spreads all over , cut down the cost of projects greatly and benefit customs.Aimed at distribution and attenuation encountered when communication over AC power wiring, this thesis tries to get over all the hardness and make sure transmit data correctly. In order to realize the target, spread spectrum, error-correcting, DSP, LonWorks and their appliances over carrier wave on power line are introduced. Besides, a model of power line transceiver is also introduced in the thesis.更多还原
