| 摘 要： | 为了减少对授权用户的干扰和降低认知用户之间的竞争,保证认知无线电系统正常通信,采用可靠性理论描述一个信道是否能够被认知用户所使用及被连续使用一段时间的概率。从空间、时域和频域3个方面联合起来研究频谱分配,仿真结果表明,三维算法的传输数据量和系统的总吞吐量的值优于贪婪算法和二维算法,有助于减少认知用户对授权用户的干扰和降低认知用户之间的竞争,表明所提算法的有效性。

| Abstract: | In order to minimize disturbance to the authorized users, and reduce competition between cognitive users, guarantee cognitive radio system normal communication, the reliability theory can describe a state of the channel, whether the channel is used or unused by the cognitive users, the probability that the channel is used continuously for a period of time. Space domain, time domain and frequency domain are joining together to cooperate in joint research for spectrum allocation, the simulation results show that the transmission data volume and the total system throughput value are improved by three dimensional algorithm. Contribute to reduce interference between cognitive users with authorized users, and competition between cognitive users is reduced. The simulation shows three dimensional algorithm is effective. |
