| 摘 要： | 由于接纳控制算法的优劣关系到网络资源能否被有效利用。文中提出了一种新的OFDMA系统的接纳控制算法。结合蚁群算法对用户需要的的总传输功率进行计算,并通过该功率对用户进行接纳控制。仿真结果表明,文中所提算法可使系统的总传输功率减小,增加用户的可接入数量,达到资源有效利用的目的。

| Abstract: | The call admission control (CAC) is playing an important role in efficient utilization of the system resources.This paper proposes a new admission control algorithm for OFDMA system.We calculated the total transmit power of users combining the ant colony algorithm,and achieved call admission control by this power of user.The proposed algorithm can reduce the total transmission power of the system and increase the number of users,thus an efficient use of the resources. |
