Implementation and performance analysis of multi-algorithm dynamic channel allocation in a wideband cellular network

This paper describes how blocking probability can be reduced using wideband technology and a multi-algorithm dynamic channel allocation mechanism in the first implemented digital cellular network. Using digital filters, signal selectivity is much better than with currently existing analog filters. For this reason frequency reuse is improved and more calls on be handled in the network at a time. Another possibility to reduce blocking probability is to use a multi-algorithm dynamic channel allocation mechanism. It includes several channel allocation algorithms implemented at the same time in the switch of a cellular network. The algorithms are selected so that each one of them provides a significant performance advantage in comparison to the others under the given traffic and interference conditions. An algorithm becomes active in the network when the actual measured offered load and interference conditions indicate that this algorithm would provide the best performance in comparison to the other algorithms implemented in the switch. The algorithm becomes passive when the traffic and interference conditions change so that another algorithm is expected to provide better performance.
