A new dynamic channel allocation scheme for microcellular systems

A new distributed dynamic channel allocation (DDCA) algorithm named combined DDCA is proposed in this paper. In this algorithm, each base station selects channels by learning through past experience of channel usage together with CIR measurement. Compute simulations are used to evaluate system performances. Performances are evaluated in two criteria, blocking probability and interruption probability. Comparisons with other DDCA algorithms have been carried out to validate the proposed algorithm.
