ESTIMATION OF NOISE DISPERSION DURING WIRELESS COMMUNICATION FOR DIVERSITY AND SCALING ASSOCIATION IN ACCORDANCE WITH LOGARITHMIC PLAUSIBILITY Russian patent published in 2009 - IPC H04L27/26 H04B1/10

Abstract RU 2346404 C2

FIELD: physics, communications.

SUBSTANCE: invention deals with methods of estimating noise dispersion in a wireless communication system. Noise dispersion estimate envisages the following: receipt of signal (402) containing an OFDM-symbol whose in-band and marginal tones include in-band pilot tones and marginal pilot tones and guard tones; estimation of effective noise dispersion with the in-band tones (702) through the in-band pilot tones and channel estimations for the in-band pilot tones; estimation of effective noise dispersion with the marginal tones (704) through the marginal pilot tones and channel estimations for the marginal pilot tones and the guard tones.

EFFECT: improvement of demodulation process due to thermal noise being taken into consideration with a single or multiple antenna(s).
