Range estimation method based on RSS measurement with limited sensitivity receiver

摘要

The present invention relates to a method for estimating the range between a radio signal emitter and a receiver. A first range estimate is obtained (330) from the signal strength of the received signal (310), a path loss model with predetermined path loss parameters (320). This range estimate is further corrected (350) with a systematic bias (340) depending upon the actual finite sensitivity of the receiver. Optionally a corrected variance of the range estimate can also be calculated (360).
