| 摘 要： | 本文结合混沌扩频与直扩脉冲幅度调制超宽带系统，基于Ad hoc网络，提出一种新的网络通信机制。该机制有针对性地解决了已有扩频Ad hoc网络系统中保密性差，码片分配效率低，节点移动造成网络拥塞等问题。经仿真验证，系统的误码率和延迟等性能有较大改善。

| Abstract: | Based on ad hoc network, a new network communication scheme is proposed that combines chaotic spread spectrum system and Direct Sequence Pulse Amplitude Modulation Ultra Wide Band System. This scheme solves several critical problems in Ad hoc network successfully, such as poor security, low PN allocation efficiency, and congestion caused by mobile nodes etc. Simulation of system error bit ratio and delay shows the network performance improves a lot. |
