One method to increase capacity in mobile communications systems is to decr
ease the cell size or service area. However, due to this area reduction, a
mobile will pass through more cells during a call. To maintain the reliabil
ity of the system, the success rate of call transfers must increase as the
cell area diminishes, preventing a ping-pong effect. Hence new and better h
andoff algorithms must be developed. Fuzzy classifier schemes are proposed
in this paper in order to select the base stations that will best serve mob
iles in a typical cellular system, The performance of handoff algorithms ba
sed on different classification techniques is discussed and evaluated throu
gh digital simulation, Results show better cell definition than the convent
ional handoff approach. For large-variance propagation channels, a reductio
n in the handoff number can be achieved, The applicability of the proposed
methodology is also discussed.
