| 摘 要： | 在underlay频谱共享模式下,提出一种认知无线电网络接入控制和功率控制的联合算法。该算法针对主用户干扰温度和次用户信号干扰噪声比(SINR)限制,通过引入冲突因子,实现网络自适应调整被拒绝参与频谱共享的次用户数目,通过迭代进行接入控制和功率分配实现频谱共享。仿真结果表明,该算法能够保证接入共享主网络频带的次用户数近似最优,而且缩短了接入控制的时间。

| Abstract: | The paper proposes a joint algorithm of admission control and power control for cognitive radio networks under the underlay spectrum sharing mode.The algorithm emphasizes on the primary user interference temperature and secondary user signal interference noise ratio restriction,by incorporating conflict coefficients,realizes the network adaptive adjustment of the number of rejected spectrum sharing secondary users.Spectrum sharing is realized by iterative admission control and power allocation.Emulation res... |
