Fuzzy technology application for mobile positioning in cellular communication
In engineering systems there is generally two classes of knowledge: objective knowledge, which can be quantified using the laws of traditional mathematics, and subjective or intelligent knowledge, that cannot be modeled mathematically but can be expressed in linguistical terms. Fuzzy Logic (FL) is …
