| Summary: | In recent years, with the rapid development of mobile communication technology,
wireless positioning technology has become an indispensable function in mobile
communication system. In these years, the research results show that in the indoor
environment, due to the complexity of the environment and positioning needs, the
Wi-Fi positioning system which has high network coverage and high positioning
accuracy is widely concerned. At the same time, due to the better stability and
signal strength of dual-band Wi-Fi, dual-band Wi-Fi is used to improve the
accuracy of positioning.
This report focuses on the location algorithm based on TDOA and RSSI. It mainly
introduces triangle positioning algorithm, three location algorithms based on
TDOA, and location fingerprinting algorithm based on RSSI. According to the
principle of various algorithms, MATLAB is used to simulate and analyze the
algorithms, and the performance of various algorithms under different conditions
is compared. In the location algorithm of TDOA, the calculation method of dual
bands Wi-Fi is proposed. |
