摘要： A method of wireless communication with improved performance employs an equalizer receiver with multiple receive antennas. Equalizer taps for linear filters of the equalizer receiver are generated by determining a conditioned covariance matrix of a first data path and a second data path based on a first gain (g0) of this first data path and a second gain (g1) of the second data path. The equalizer taps of the first data path and the second data path are determined based on the conditioned covariance matrix. The first data path and the second data path are then equalized using the equalizer taps. An equalized signal is generated by combining the equalized first data path with the equalized second data path.

摘要： In a method for image prediction of a multi-view video codec, a disparity vector value of a current macroblock is obtained and a corresponding macroblock is searched through the obtained disparity vector value. An intra prediction coding direction value of the searched macroblock is determined as an intra prediction coding direction value of the current macroblock. The current macroblock is coded/decoded through the determined intra prediction coding direction value. The coding efficiency can be increased by reducing a coding amount by omitting a process of obtaining an unnecessary disparity value by using a different-view intra prediction coding direction as a current-view intra prediction coding direction. The coding efficiency can be increased by reducing a coding amount by differentially coding a similar disparity vector. The reliability can be increased through an accurate disparity using multiples of 8 rather than 16, in motion skip for sharing the format of a macroblock.

摘要： The present invention relates to a method for selecting an appropriate mode when performing a new broadcast, such as a 3D stereo broadcast, a UHDTV broadcast, and a multi-view broadcast, among others, while maintaining compatibility with existing broadcasting channels in an MPEG-2-TS format for transmitting and receiving digital TV, and to a method for recognizing a descriptor. To this end, the present invention suggests providing the descriptor which is related to synthesizing left and right images using the type of stream, existence of the descriptor, and a frame-compatible mode flag.
