Performance analysis of a channel assignment scheme in cellular communication systems

In cellular communication systems, channel assignment schemes are very important to improve teletraffic performance characteristics. Because of the overlapping design of the cells in cellular communication systems, a mobile user is capable of communicating with two different bases. In this paper, a new channel assignment scheme is proposed to improve the blocking probability of a cellular communication system. The blocking probability of the cellular communication systems is analyzed based on Markov chain. According to the analytical results, the proposed channel assignment scheme shows different characteristics in comparison with fixed channel assignment scheme.
