Abstract
This paper investigates the performance of distributed dynamic channel assignment (DDCA) strategies in sector cell layout systems using directional antennas. Simulations are done under the same propagation conditions and with the same system parameters. They show that DDCA strategies in sector cell layout systems gain 2.3/spl sim/8.2 times higher capacity than do the fixed channel assignment (FCA) strategy in conventional cellular systems using omnidirectional antennas and 1.5/spl sim/2.5 times higher than do DDCA strategies in conventional systems.
