Bit Allocation Scheme With Primary Base Station Cooperation In Cognitive Radio Network |
Abstract | ||
|---|---|---|
Bit allocation scheme for cognitive OFDM with base station cooperation (BSC) in primary network is discussed in this correspondence. Under this circumstance, the optimization problem is formulated to minimize the interference to the primary BSC network, in order to guarantee the fixed rates for cognitive user transmission. With the knowledge of channel state information (CSI) in the interference channel, the optimal solutions can be solved by Lagrange optimum methods. Furthermore, bit assignment and access ability of cognitive users are analyzed in BSC model. Relationship of primary interference power and secondary allocated bits are presented. Simulation results indicate that, the access ability of cognitive user is significantly enhanced by BSC in comparison with non-cooperative primary network scenario, and the corresponding interference power could be reduced significantly with the proposed optimal bit assignment scheme. |
