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.

System and method for providing sub-band whitening in the presence of partial-band interference

In one preferred embodiment, polymers are provided that comprise a structure of the following Formula (I): Photoresists that comprises such polymers also are provided.

Monomers, polymers and photoresist compositions

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.

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.

Communication receiving device and method for operating the same

New photoresists are provided that are useful in a variety of applications, including negative-tone development processes. Preferred resists comprise a first polymer that comprises (i) first units comprising a nitrogen-containing moiety that comprises an acid-labile group; and (ii) second units that (1) comprise one or more hydrophobic groups and (2) are distinct from the first units.

Photoresist compositions and methods

An orthogonal frequency division multiplexing (OFDM) receiver includes a n average power calculation unit and an output unit. The average power calculation unit calculates and outputs a first average power of a null symbol section of each transmitted frame output from an OFDM transmitter and calculates and outputs second average powers of sub-carriers that correspond to each null symbol section. The output unit compares the first average power and the second average powers, to perform a reciprocal transformation on difference values of the first average power and each of the second average powers based on results of the comparisons, and to store and output reciprocally transformed values as channel state information.
