Abstract
A frequency hopping communication system uses measured intensity values, such as RSSI (received signal strength indication) values, of RF signals previously received on a particular channel to generate a signal threshold that is tailored for the particular channel and is to be applied to subsequent frequency hopping processes. The signal threshold is used for determining whether a received RF signal is from an actual transmission or is merely background noise.
