    • Aspects of a method and system for redundancy-based decoding of video content are provided. A bit sequence comprising video content may be decoded in a multilayer process based on a decoding algorithm and at least one physical constraint. The decoding algorithm may be based on the Viterbi algorithm. Whether the bit sequence comprises video content may be determined based on information provided by a portion of a packet header or by packet priority information necessary for enabling quality of service applications. The physical constraint may be based on border, DC component, and/or low frequency continuity between neighboring discrete cosine transform (DCT) blocks. The physical constraint may also be based on the consistency of video data coded by a variable length coding (VLC) operation. At least one physical constraint test may be performed on selected estimated video bit sequences to select a decoded output video bit sequence.
    • 提供了一种用于视频内容的基于冗余解码的方法和系统。 可以在基于解码算法和至少一个物理约束的多层过程中解码包括视频内容的比特序列。 解码算法可以基于维特比算法。 可以基于由分组报头的一部分提供的信息还是通过为实现服务质量应用所需的分组优先级信息来确定比特序列是否包括视频内容。 物理约束可以基于相邻离散余弦变换(DCT)块之间的边界,直流分量和/或低频连续性。 物理约束也可以基于通过可变长度编码(VLC)操作编码的视频数据的一致性。 可以对所选估计的视频比特序列执行至少一个物理约束测试,以选择解码的输出视频比特序列。

    • A method for successive interference cancellation in code division multiple access (CDMA) systems is provided that uses variable interferer weights. This method allows interfering signals to be cancelled in order to recover a transmitted data signal. This method involves receiving the data signal subject to interference from at least one interfering signal. A first interfering signal is identified. Then an interferer weight coefficient associated with the first interfering signal is generated. This allows the first interfering signal to be cancelled from the received data signal using the interferer weight coefficient. These processes may then be reiterated for other interfering signals. It is then possible to recover the transmitted data signal from the received data signal.
    • 提供了一种使用可变干扰权重的码分多址(CDMA)系统中的连续干扰消除的方法。 该方法允许消除干扰信号以恢复发送的数据信号。 该方法涉及从至少一个干扰信号接收受到干扰的数据信号。 识别出第一干扰信号。 然后产生与第一干扰信号相关联的干扰源加权系数。 这允许使用干扰源权重系数从接收的数据信号中消除第一干扰信号。 然后可以重复这些处理用于其他干扰信号。 然后可以从接收到的数据信号恢复发送的数据信号。
