A New Algorithm for WIFI Position Positioning Based on PGD
When using the position coordinates of known fingerprint points to estimate the location of location points, most WKNN is used. Considering that the AP signal has different decay rates in different directions, this paper proposes a new position positioning al-gorithm based on PGD on the basis of WKNN. Through the experimental analysis, the results show that compared with WKNN, the PGD algorithm proposed in this paper has higher positioning accuracy and better reliability.
