摘要： A decoder generates distance and label metrics associated with each label of a coset transmitted in a multi-input multi-output communication system having Mt transmit antennas and Mr receive antennas by performing 2(“u+n”)(Mt−1) searches, where n is the number of encoded bits used to identify one of 2u cosets at the transmitting end and u is the number of unencoded bits used to select one of 2u labels at the transmitting end. The decoder forms an intermediate vector quantity associated with one of the transmit antennas to compute the metrics associated with each of the remaining transmit antennas. The decoder then forms a second intermediate vector quantity to compute the metrics associated with the transmit antenna that was used to form the first intermediate variable. The metrics so computed are used by a Viterbi decoder to identify the coset and the most likely transmitted label in that coset.
摘要翻译：解码器通过执行2（“u + n”）（Mt-1）搜索，生成与具有Mt个发送天线和Mr个接收天线的多输入多输出通信系统中发送的陪集的每个标签相关联的距离和标签量度，其中n是用于识别发送端的2u陪集中的一个的编码比特数，u是用于在发送端选择2u个标签之一的未编码比特数。解码器形成与发射天线之一相关联的中间矢量，以计算与每个剩余发射天线相关联的度量。然后，解码器形成第二中间矢量，以计算与用于形成第一中间变量的发射天线相关联的度量。如此计算的度量被维特比解码器用于识别该陪集中的陪集和最可能发送的标签。

摘要： Beamforming may be used in MIMO communication systems to further enhance spectral efficiency. Beamforming refers to beamed transmissions to a single destination (e.g., a station) at a time, to enhance the rate and/or range of transmission. To perform beamforming from a source to one or more destinations, a channel and/or beamforming matrices corresponding to the channel needs to be known at the source, which may be obtained as feedback from the destination. However, the beamforming matrices may not be smooth over frequency as it is fed back from the destination. Therefore, certain aspects of the present disclosure provide beamforming feedback options, resulting in the smoothness of a beamforming matrix.
摘要翻译：波束形成可以用于MIMO通信系统中以进一步提高频谱效率。波束成形是指一次向单个目的地（例如，站）的波束传输，以增强传输的速率和/或范围。为了从源到一个或多个目的地执行波束成形，需要在源处知道对应于该信道的信道和/或波束成形矩阵，其可以作为来自目的地的反馈获得。然而，当从目的地反馈时，波束形成矩阵可能不是频率上的平滑。因此，本公开的某些方面提供波束成形反馈选项，导致波束形成矩阵的平滑度。
