All-channel concentric allocation in cellular systems
T. Takenaka, T. Nakamura, Yoshiharu Tajima · 2002
A dynamic channel assignment algorithm for cellular systems, i.e., all-channel concentric allocation (ACCA), is proposed, and its performance is evaluated by computer simulation. Computer simulations show that system capacity (offered traffic at a blocking rate of 3%) is improved by a factor of 2.5 compared to conventional fixed channel assignment (FCA). A transmitter power control (TPC) is designated to cooperate with ACCA and enhance system capacity. Simulations confirm that ACCA with TPC accomplishes a system capacity 3.4 times greater than FCA.>
