摘要
分析了蜂窝移动通信系统信道指配策略中的一个重要策略———借用策略,包括最早出现的简单借用策略,到后来在此基础上发展而来的带信道序号的借用策略(BCO) 和带方向锁定的借用策略(BDCL) 。在原指配策略的基础上,增加了共道信道中的被锁定信道在信道表中的位置的处理,澄清了原策略中在这一点上的模糊不清。同时,通过两个方面的措施优化了BCO 和BDCL算法。
Borrowing strategy is an important strategy in channel assignment of cellular mobile communication systems and includes the early presented simple borrowing strategy and the later developed borrowing with channel ordering (BCO) and borrowing with directional channel locking (BDCL). Based on the analysis of the borrowing strategy, this paper suggestes a method to handle the location of the locked channels in the cochannel interfering cells, and clarified some confusions in the original channel assignment strategies. Furthermore, two measures are taken to optimize the algorithms of BCO and BDCL. Simulation results show that the optimized algorithms can obviously reduce the complexity of the original algorithms for BCO and BDCL.
