| Abstract | In this paper, the spectrum allocation scheme has been proposed to enable complete spectrum sharing in multi-user MIMOcognitive radio (CR) systems. Performance analysis has been developed to evaluate bit error rate (BER) of each secondary user(SU) because of the e ect of node member positions in multi-user CR network. In order to achieve this SUs which are ready toreceive data and can communicate by ignoring any damage caused to the primary user (PU)'s communication at the same time.The authors have successfully used this method to process each frequency channel and to allocate channel to the appropriateSUs. The advantages of this system are as follows: 1) the performance analysis is able to support multi-user CR systems, 2)this research can clearly indicate the e ect of the positions of node members in the CR network on their service quality, 3)the impact on both downlink and uplink operations are combined in order to make the final decision for communication, and4) the spectrum allocation scheme which is able to allocate frequency channels for all users in CR systems is presented. Thesimulation results that are provided, show the performance of SU in term of BER inside their coverage areas along with thee ect of GPS error. The results present the complete allocation of spectrum sharing for multi-user CR systems. The outcomeof this research is very useful in further development of CR systems. In addition to this, it can be easily implemented inpractice at the stage of spectrum sharing. Each SU can decide for themselves whether their position is adequate for goodquality communication or not. |
