Abstract
Systems, methods, and other embodiments associated with estimating noise in a receiver device based on related properties of order statistics are described. According to one embodiment, a method includes generating an initial set of magnitude squared values from a time domain impulse response of a receiver device. The method also includes generating an initial noise power estimate based on a modified set of magnitude squared values and generating a threshold value based on the initial noise power estimate. The method generates a final noise power estimate by averaging values of the initial set of magnitude squared values that are less than the threshold value and removing a thresholding bias from the resulting average.
