A dynamic channel assignment algorithm for cellular system with adaptive array antennas

摘要

In this paper, a new dynamic channel assignment algorithm suitable for adaptive array antennas in cellular system is proposed. By this algorithm, stronger co-channel interference is cancelled by directional beam pattern with higher priority. With3-element array antenna, conventional algorithm shows 2.7 fold capacity increase compared with an omni antenna system, whereas proposed algorithm shows around 3.3 fold capacity increase, at the point of 3 percent blocking probability. The simulationresults also show that a shorter reuse distance can be achieved by the proposed algorithm, which indicates a more efficient utilization of channel resource.
