摘　　要：介绍了一种蜂窝移动通信系统中基于紧凑模式的信道借用指配策略 (CPCB)的优化策略———基于紧凑模式带方向锁定的信道借用指配策略 (CPCBDL)。这种策略不仅将带方向锁定的优点引入到CPCB策略中 ,而且优化了信道管理机制。将新算法在一种普遍采用的蜂窝网络上进行仿真 ,分别获得了在一种均匀和两种非均匀模式业务分布下的系统性能。结果表明 ,CPCBDL的系统性能不仅明显优于FCA ,BDCL和基于CP的DCA等策略 ,也优于CPCB策略。The authors propose an optimized compact pattern based channel borrowing assignment (CPCB) strategy, that is, the compact pattern based channel borrowing assignment strategy with directional locking (CPCBDL). This strategy not only introduces the advantage of directional channel locking concept, but also optimizes the mechanism of channel management. Simulation is done in a universally used network. The system performances under a kind of uniform and two kinds of non-uniform traffic distributions. The simulation results show that the CPCBDL performances are superior to those of FCA, BDCL and CP based DCA, etc., and even outperform those of CPCB. This improvement is very important to improving the spectrum efficiency and throughput in cellular communication systems.
