ABSTRACT:
Digital calculation of an RSSI value begins by digitally calculating a magnitude of a signal (e.g., a received RF signal or representation thereof). The process then continues by filtering the magnitude of the signal to produce a filtered magnitude signal. The process then continues by determining a coarse RSSI value of the filtered magnitude signal, wherein the coarse RSSI value indicates a sliding window of RSSI values. Once the coarse RSSI value is obtained, the process continues by determining a fine RSSI value within the sliding window of RSSI values. The process concludes by summing the fine RSSI value with the coarse RSSI value to produce a digital RSSI value.
