Abstract: An accurate and fast method for estimation of noise power in digital communication systems is presented. Exemplary embodiments of the present invention do not rely upon the need for embedding reference sequences in the transmitted data. Accordingly, such exemplary embodiments are especially suited for tracking variations of noise power in digital communication systems with fast fading channels.
