Investigation on a dynamic channel allocation for high capacity mobile radio systems

The potential of a dynamic channel-allocation scheme is described, in particular, to increase the system capacity and to counteract the traffic bursts typically experienced in cellular mobile radio systems as a consequence of traffic jam, accidents, traffic lights, etc. In order to accomplish these improvements, an effective procedure, monitoring the link quality of all the active calls, is required. Practical considerations necessitate implementation such a control just at the base station. The affordability of this approach is considered, assuming as input parameters the correlation among wanted and interfering signals in both mobile-to-base and base-to-mobile directions. A software simulation of cellular systems with a broad range of applications has been used to evaluate the feasibility of such a channel assignment method
