超宽带基于分组碰撞的多用户干扰模型在ad-hoc网络中的应用

Application of a multiple-user interference model based on packets collision(PC)in UWB system in ad-hoc network

在多用户UWB(超宽带)系统中,为了减小MUI(多用户干扰),提出了一种基于分组碰撞的多用户干扰(PC)模型。这种模型相比较SGA(标准高斯)模型,更适用于用户数量较少,传输速率较低,存在主导地位的干扰时,例如考虑异步网络:ad-hoc网络,更适用于采用PC模型。

In Ultra-Wideband Multiple Access Communication Systems, multiple-user interference （MUI） is expected to adversely affect system capacity and performance. This paper investigates a multiple-user interference model based on packets collision（PC）. Comparaed with the SGA model,the PC model is better when the users are less and the transmit rate are low,such as the ad-hoc network.
