摘要：
The invention relates to a system and method for localization positioning in lighting systems. At least two of a Time Difference of Arrival (TDOA), Angle of Arrival (AOA), Received Signal Strength Index (RSSI) and a Position Estimation Algorithm with unified TDOA and RSSI are used to obtain localization positioning. The schemes introduce a maximum-likelihood estimation strategy incorporating a partial derivative matrix for each lighting unit using at least two reference nodes in order to achieve higher accuracy.
