摘　　要：文章以HomePlug AV标准的自适应电力线通信调制解调器为基础,分析了该标准的分层体系结构,简要介绍了宽带电力线通信技术和自适应均衡技术。选择OFDM作为调制技术,并对此进行了参数设计,重点设计了电力线调制解调器中自适应均衡的软实现方案,最后给出了自适应调制解调器的整体电路。Based on the self-adaptive PLC modem of HPAV standard, this paper analyzes the layered structure of this standard and introduces the broad band PLC and self-adaptive equalization technology. OFDM is selected as the modulation technology, its parameters is designed and the software scheme is introduced emphatically. At last, an integrated circuit of self-adaptive PLC modem is also put forward.
