    • A method for constructing a space-time/space-frequency code, and a transmitting method and apparatus are provided, which relate to the field of wireless communication technologies. The method for constructing a space-time/space-frequency code includes: classifying at least two transmitter antennas into K groups, and classifying information symbols into K′ groups; constructing a Toeplitz matrix for information symbols in each group according to the number of transmitter antennas in a transmitter antenna group; and substituting the Toeplitz matrix for nonzero elements in an Orthogonal Space-Time Block Coding (OSTBC) matrix that is based on K and K′, and when the OSTBC matrix comprises a zero element, substituting a zero matrix with a corresponding dimension, for the zero element. The space-time code constructed with the above method has orthogonality.
    • 提供了一种用于构建时空/空频码的方法,以及与无线通信技术领域有关的发送方法和装置。 用于构建空时/空间频率码的方法包括:将至少两个发射机天线分类为K个组,并将信息符号分类为K'组; 根据发射机天线组中发射机天线的数量,构建每组中的信息符号的Toeplitz矩阵; 并将Toeplitz矩阵替换为基于K和K'的正交空时块编码(OSTBC)矩阵中的非零元素,并且当OSTBC矩阵包括零元素时,用相应维度替换零矩阵,对于 零元素。 用上述方法构建的时空代码具有正交性。

    • Disclosed herein are representative embodiments of generating representative motion information that can be used during processing of a video frame. In one exemplary embodiment disclosed herein, a reference frame comprising a group of blocks is processed, and motion information for the group of blocks is compressed at least by buffering representative motion-vector information and representative reference-frame index information for the group of blocks. The representative reference-frame index information comprises reference-frame index information of a representative block of the group of blocks, and the representative reference-frame index information represents reference-frame index information for the group of blocks during processing of a current frame.
    • 这里公开了生成可以在视频帧的处理期间使用的代表性运动信息的代表性实施例。 在本文公开的一个示例性实施例中,处理包括一组块的参考帧,并且至少通过对代表块的代表性运动矢量信息和代表参考帧索引信息进行缓冲来压缩该组块的运动信息。 代表参考帧索引信息包括块组的代表块的参考帧索引信息,代表参考帧索引信息表示当前帧的处理期间的块组的参考帧索引信息。
