METHOD AND DEVICE FOR NOISE FLOOR ESTIMATION

摘要

A method for determining the noise floor in a receiver includes sorting received estimated values of the noise floor by time bins in a time cycle, determining and storing the average value of the received values in each time bin for a previous time cycle, and determining a scale factor for each time bin in the current time cycle by dividing the average value of each time bin in the previous time cycle by the smallest average value of the time bins in the previous time cycle. The division for time bin k in the previous time cycle is used as scale factor for time bin k in the current time cycle. A compensated noise floor power level for each time bin in the current time cycle may be determined by applying the scale factor of the current time bin to the currently received estimated value.
