Abstract
A noise power estimator, comprising: a first subtractor configured to generate at least one first signal by subtracting a reconstructed interference signal from a symbol of a received first time-domain training sequence; a second subtractor configured to generate at least one second signal by subtracting an estimated value for the first time-domain training sequence from one of the at least one first signal; an averaging circuit configured to generate at least one square average value by average the at least part of the at least one second signals; and a detector configured to detect a minimum value among the at least one square average value and output the minimum value as a noise power estimation value.
