| Abstract: | An integrated base station assignment, diversity and power control algorithm is proposed to realize the base station sharing, in which primary users (PUs) and secondary users (SUs) can connect to any base station by the variable base station assignment, so that the radio resource is efficiently utilized for cognitive radio networks. We show that this algorithm reduces SU's outage rate (for failing to meet the requirement of SINR per bit) while always meeting the requirement of SINR per bit for all PUs. |
