Outage Probability of Cognitive Relay Network Considering the Interference from Primary Users on the Secondary Relay and Reciver
Journal Title: روش های هوشمند در صنعت برق - Year 2017, Vol 8, Issue 30
Abstract
Cognitive Relay network is a plan to remove some problem such as the limited Coverage and limited spectrum. This strategy permit secondary users to use a frequency band( spectrum), which is dedicated to the primary users. The secondary networks employ a relay node to extend the communication range. Also the relay using to improve the outage probability of the network.For coexisting between primary and secondary network, it is necessary that the secondary network control the transmit power in their networks. Primary and secondary users have interference effect on each other. In this paper we consider both interference. In addition to the provision on the transmit power of the secondary users We consider the effect of the interference cause by primary user on secondary network. The aim is to show the effects of interference caused by primary users on the correct information and the outage probability in the cognitive relay network.
