摘要:
A method for determining a scaling factor in a communication system. The method includes calculating an average power for each of an input signal and an output signal of a channel predictor; calculating a noise variance using the calculated average power; normalizing the noise variance with an average power of the channel predictor's output signal; and determining a scaling factor using the normalized noise variance.
