Abstract:
In order to enhance the linearity and prec ision of m easurem ent system, a new me thod of d istance m easuring based on LQ I is applied to indoor lo ca lization system in th is paper. Exper im ents are carr ied out on ZigBee-based hardw are p la tform s in indoor circum stance. A ccording to the experim enta l data, the sc ientific m odeling o f indoo r d istance m easurement is produced. The resu lts indicate that LQI has a good linear ity and precision on m easur ing sho rt distance, and can ach ieve be tter results in indoor distancem easurem ents.
