Abstract: A method and system for providing sub-band whitening are herein provided. According to one embodiment, a method includes deriving an estimated noise plus interference variance (NIVar) based on at least one legacy-long training field (LLTF) symbol from an LLTF signal; and updating an interference whitening (IW) factor by using a sub-band NIVar.

Abstract: A method and system for providing sub-band whitening are herein provided. According to one embodiment, a method estimating an interference whitening (IW) factor based on a legacy-long training field (LLTF) signal, updating the estimated IW factor during transmission of a data symbol, and scaling the data symbol based on the updated IW factor and the estimated IW factor.

Abstract: A communication receiving device is provided. The communication receiving device includes a cross-correlation measuring circuit which receives an L-SIG (Legacy signal) symbol and a RL-SIG symbol to measure a cross-correlation degree therebetween, an accumulating circuit which accumulates a real part of a cross-correlation degree measurement value, a comparator which compares the accumulated L-SIG symbol and the RL-SIG symbol with a variable threshold value, and a threshold value calculator for calculating the threshold value.
