The reception gain decision unit (42) decides the gain according to the maximum RSSI among the RSSI detected by the RSSI detection unit (32) and the demodulation-enabled range of the sub channel in which the maximum RSSI has been detected.
The non-NSC RSSI is calculated (410) by subtracting a respective RSRP from a total RSSI.
An impedance measurement system (IMS) is provided that comprises an RSSI chain (RSSI), a limiter RSSI chain (LIMRSSI) and a limiter chain (LIM).
The apparatus includes: a first RSSI measuring unit, an RSSI deciding unit, an RSSI sorting unit and a frequency sweeping unit.
The first and second RSSI profiles are compared to determine a direction of travel of the object.
The RSSI values for wireless signals received from the APs are acquired, as is an RSSI heatmap.
In an example embodiment, the RSSIs are adjusted, and the adjusted RSSIs for each floor are summed.
The processing circuitry may gather additional RSSI values in one or more frequency channels and may adjust the additional RSSI values based on the associated RSSI offset values.
The output of each RSSI detector is coupled to an associated comparator that compares the intermediate RSSI value against a corresponding threshold.
A difference RSSI value or an average RSSI value for each of the plurality of signal frequencies is determined.
The RSSI heatmap information may be, e.g., the transmission power data or a RSSI heatmap.
Known RSSIs between APs can be employed for comparing measured RSSIs with the known RSSIs to determine the probability that the wireless device is within the cell of each AP.
The processor is also configured to estimate a Receive Signal Strength Indicator (RSSI) of the received signal, and to subtract the signal power associated with the second transmission from the estimated RSSI to obtain a modified RSSI.
The RSSI chain and the limiter RSSI chain are connected to a subtraction circuit (SC) and the limiter RSSI chain and the limiter chain are connected to a phase detector (PD).
To differentiate between different types of modulation, a fast RSSI detector performs an RSSI measurement on a received signal.
