摘要

分析了认知超宽带网络的容量

考虑到传输功率限制和主系统接收端的干扰温度限制

通过半解析的方法计算出网络的中断概率和最大支持的用户数

并且通过仿真验证了对容量的分析。仿真表明如果增加主系统的干扰温度限

那么认知UWB网络的容量将极大下降

并且传输功率限制和干扰温度限制之间有一定的相关性。

Abstract

The problem of analyzing the capacity of cognitive UWB networks was investigated.Taking into account of several factors such as transmission power constraints

interference temperature constraint in the receiver of primary system

outage probability and maximum allowed users were calculated by semi-analytical approach.Simulations were provided to illustrate the analysis.It is also proved that the increase of interference temperature will deteriorate the capacity of cognitive UWB network;and the constraint of interference temperature is related to the constraint of transmission power.
