【 摘 要 】

This paper introduces a performance analysis of a multi-user spectrum sharing based the effect of node positions in an MIMO cognitiveradio(CR)network.Theobjectiveisto developand enablereliableCRtechnology.Thispaper:1) developsthe performanceanalysistosupportmulti-userCRsystems,2)describesthesignificanteffectofeachnodepositionandthe distancebetweenthem,3)combinesdecisionresultson both downlinkanduplink operations,and,4)presentsaspectrum allocation method for all users in CR systems. The simulation results show the performance of secondary users in terms of thebit error rate inside their coverage areas together with the effect of GPS error. Finally, a completeself-evaluation guideline of the overlapping spectrum sharing for multi-user CR systems is presented. The outcome of this paper is very useful to enhance CR systems. Also, it can be easily implemented in practice for spectrum sharing. The users can realize by themselves whether their positions are in the available area or not.
