Abstract

This paper presents the first closed-form analysis of cochannel and adjacent channel reuse ratio distributions in dynamic channel assignment (DCA) cellular systems and compares the results with conventional fixed channel assignment (PCA) cellular systems, Computer simulations show that DCA systems exhibit significantly closer cochannel and adjacent channel frequency reuse than FCA systems for a significant proportion of terminals, Mathematical analysis is used to show that this is a fundamental consequence of DCA channel pooling and that the resultant interference distributions cannot be obtained using conventional cellular engineering techniques. The closed-form expressions derived establish a theoretical lower limit to channel reuse in DCA cellular systems.
