| 摘 要： | 对于基于CDMA的移动Ad hoc网络，传统方案下其终端对接收到的数据用匹配滤波器进行检测，该文则将多用户检测器引入到Ad hoc网络的终端中，通过抑制多址干扰来提高网络的整体性能。基于全连接有限元模型，并在介质访问子层采用时隙ALOHA协议的基础上，详细推导了Ad hoc网络的吞吐量。理论分析和实验仿真都说明多用户检测可以显著地提高Ad hoc网络的吞吐量。

| Abstract: | The importance of multiuser detection for CDMA-based mobile Ad hoc network is addressed in this paper. Different from conventional scheme, each terminal of the Ad hoc network in this paper is equipped with an adaptive blind linear multiuser detector. Employing slotted-Aloha protocol in MAC layer, and following full-connected network model, the throughput of Ad hoc network is studied. Theoretic analysis and simulation results show that multiuser detection can remarkably improve throughput performance ofAd hoc network. |
