本论文主要以IEEE802．1ln协议1.0版本草案为基础，研究的主要内容有两个。第一是研究了802．1ln协议介质控制访问层(MAC)的聚合帧、帧结构简化、预约时间、PSMP等多种有效提高网络吞吐量的关键技术。第二是研究了802．1ln协议中物理层的信道估计技术。-This paper mainly IEEE802.1ln basis of the draft version 1.0 protocol, the study has two main elements. The first is control of the media access layer 802.1ln protocol (MAC) of the polymer fr a me, the fr a me structure, simplify, make an appointment, PSMP effectively improve the network throughput and other key technologies. The second is to examine the 802.1ln protocol physical layer channel estimation.
