Ad hoc网络物理层关键技术

Ad hoc Network Crucial Technique in Physical Layer

目前移动自组织网(Ad hoc Network)被越来越多的方面应用,对它的研究也越来越多的关注。由于网络结构的特殊性,其物理层的安全性,信道及调制方式等均有其特殊要求。本文中在Ad hoc物理层采用跳频正交频分复用的调制方式,并讨论了其同步问题。

Now, because ad hoc networks have been applied in many areas, so people have given it more and more attentions. For the particular configuration network, it is corresponding considered of the security, channel and modulation in physical layer. In this paper,we adopt frequency-hopped OFDM modulation and discuss the synchronization of FH-OFDM communication system in physical layer.
