摘要

本文研究了多节点共存的CUWB系统模型。在假设干扰节点在认知节点区域内为高斯分布的基础上,采用中断概率来评价系统的性能。理论分析和数值模拟表明,干扰节点密度、分布区域半径和干扰阈值都对多节点共存系统的性能有影响。

Outage Probability of Multinode Coexistent CUWB System
In this paper, a CUWB system model with coexistence of multinode is studied. Based on the assumption that interfering nodes are Gaussian distribution in cognitive node’s region, outage probability is used to evaluate the performance of system. Theoretical analysis and numerical simulations indicate that density of interfering nodes, radius of the distributed area and interference threshold all have impact on the multinode coexistent system performance.
