    摘要： 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.

    摘要： 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.
