Abstract

In this paper we analyze the outage performance of a dual hop cognitive underlay network employing a decode and forward relay. The analysis has been modeled over extended generalized K fading channel taking the interference temperature as a constraint so that the transmit power of the secondary source and relay do not exceed this limit. This results in constraints on the transmit powers of the secondary network also and hence ensures no interference with the primary communication which is imperative in cognitive underlay systems. The analytical expression for the outage probability is derived employing the probability density functions and the cumulative distribution functions of the channel gains for the various links in the system. The expression for the outage probability is calculated in terms of Fox's H functions. Our results demonstrate the dependence of outage probability performance on various parameters of the system under the power constraints already defined. The analytical results are verified with the help of MATLAB simulations.

EGK衰落信道上df中继认知底层网络的中断分析

本文分析了采用译码转发中继的双跳认知底层网络的中断性能。以干扰温度为约束，在扩展广义K衰落信道上对分析进行建模，使二次源和中继的发射功率不超过该限制。这也限制了二级网络的传输功率，从而确保不干扰初级通信，这在认知底层系统中是必不可少的。利用系统各环节信道增益的概率密度函数和累积分布函数，导出了中断概率的解析表达式。中断概率的表达式是根据Fox的H函数计算的。我们的结果证明了在已定义的功率约束下，停电概率性能与系统各参数的依赖关系。通过MATLAB仿真对分析结果进行了验证。
