摘要: In this paper, we consider the design of access schemes for secondary users in cognitive radio systems based on primary user feedback information. We a employing random scheme with an probability that depends state. show proposed can enhance system performance terms throughput and/or delay while guaranteeing certain quality service (QoS) user; is due to fact avoids sure collisions between and users. The be deployed any other it always results gain using extra piece information coming from feedback.
