Trying to undestand received signal strength indicator (RSSI)

Hi just get interested in Beacon technology, I read a lot about RSSI algorithm in numerous journal papers. Can anyone help me on how to read or understand the algorithms. Is there any link that I can refer about RSSI algorithm.

Thanks

RSSI is not really an algorithm, it’s just a measure of how strong the received signal is (:
