ABSTRACT:
Methods, systems and apparatus for estimating statistical properties of noise in modulated data carrier signals represented by modulated data symbols are disclosed. The method comprises generating an instantaneous estimate of the statistical property of noise from the received modulated data symbols on a sample by sample basis and applying a compensation function to the instantaneous estimate. The method further comprises averaging an output of the compensation function to determine the estimated statistical property of noise.
