Localization algorithm for GSM mobiles based on RSSI and Pearson's correlation coefficient

For GSM localization, an algorithm is developed with received signal strength indication(RSSI) and Pearson's correlation coefficient. Based on Cell-Id method. Redundant information from seven base stations is fully utilized to strengthen the localization accuracy. Our method does not need additional device or prior statistical knowledge. Simulation and field experiment are implemented for performance verification. Compared with typical algorithms such as Cell-Id and the Minimum Variance Localization, our proposed algorithm can achieve better accuracy.
