Method and device for noise floor estimation

A device for determining a noise floor power level in a radio receiver, the device comprising:

• one or processing circuits, the processing circuits configured to operate as:
• an averaging circuit configured to:
• receive estimated values of the noise floor power level;
• sort the received estimated values by time bins, the time bins being N predetermined portions of a predetermined time cycle;
• determine an average value of the received values in each time bin for a previous time cycle;
• a scale factor circuit configured to:
• receive, from the averaging circuit, the average values of the bins for the previous time cycle;
• determine a scale factor for each time bin k in the current time cycle by dividing an average value of each time bin k in a previous time cycle by a smallest average value of the time bins in the previous time cycle;
• a determining circuit configured to determine a compensated noise floor power level for each time bin in the current time cycle by applying the scale factor of the current time bin to the currently received estimated value of the noise floor power level.
