Abstract :
The effect of adjacent cell interference on the system capacity is investigated. Hexagonal and circular cell approaches are used. The amount of interference from the six adjacent cells of the first tier is obtained by a numerical method in the hexagonal cell approach. We use a circle to approximate the hexagonal cell and a closed-form solution is obtained. By the circular cell approach, the adjacent cell interference function is derived. The total adjacent cell interference is found by the adjacent cell interference function obtained. Generalization of the analysis to an irregular cell structure is also presented
