  • Patent number: 8711019
    Abstract: A system including a binarization module, a prediction module, and a shifting module. The encoding module is configured to encode symbols using context-adaptive binary arithmetic coding, in which the symbols are generated by binarizing a syntax element. The prediction module is configured to generate a prediction for a number of renormalizations to be performed to renormalize an interval range when encoding one of the symbols. The shifting module is configured to generate a renormalized interval range by shifting the binarized syntax element R times, where R is a number of leading zeros before a 1 in the binarized syntax element. The encoding module is configured to encode a next symbol following the one of the symbols based on the renormalized interval range.

  • Publication number: 20130336429
    Abstract: Embodiment of the disclosure set forth methods for processing a signal received at a receiver in a wireless communication system in a time slot. Some example methods include obtaining an estimated transmit signal for a transmit antenna of the wireless communication system. The estimated transmit signal may be illustrated on a constellation diagram in accordance with a modulation scheme of the wireless communication system. Example methods further include calculating a distance between the estimated transmit signal and a corresponding constellation point on the constellation diagram. The corresponding constellation point is the closest constellation point for the estimated transmit signal among all constellation points in accordance with the modulation scheme of the wireless communication system. Example methods further include determining whether the transmit antenna is likely to transmit the signal received at the receiver based on the distance.

  • Patent number: 7982641
    Abstract: A system including a binarization module, an encoding module, and a prediction module. The binarization module is configured to binarize a syntax element and to generate symbols. The encoding module is configured to encode the symbols using context-adaptive binary arithmetic coding (CABAC). The prediction module is configured to generate a prediction for a number of renormalizations to be performed to renormalize an interval range when encoding one of the symbols. The encoding module encodes a next symbol following the one of the symbols based on the prediction before renormalization of the interval range is actually completed.

  • Publication number: 20090235468
    Abstract: The instant invention relates to new polymers which enhance the wet slipping properties of textiles and thus reduce friction during the treatment process. The polymers are produced from the reaction product of diamines with a polyoxyalkylene glycidyl ether and dicarboxylic acids. Advantageously the instant polymers are used in aqueous emulsions which may contain further additives.

  • Patent number: 4975336
    Abstract: this invention relates to an alloy material for data storage of magneto-optical disk (ADSMO), as well as its manufacturing process. ADSMO is based on manganese, bismuth and doped with aluminum atoms and silicon atoms or by aluminum atoms and boron atoms. The above mentioned elements are deposited onto a transparent substrate in a certain sequence using an evaporation process or sputtering process, and then compact hexagonal cyrstalline structures are formed after being annealed in vacuum. ADSMO has a large magneto-optical Kerr rotation, a small size of crystal grains and a stable structure; its manufacturing process is easy and simple.
