摘要：
A plurality of wireless channels link a transmitter and a receiver, each channel corresponding to a different transmit-receive antenna pair. Channel state information is estimated for the plurality of wireless channels by grouping the plurality of channels into one or more groups, each group including the channels associated with two or more collocated transmit and/or receive antennas. A set of delay tap values is iteratively estimated in the time domain for each group of channels so that the channels included in the same group are associated with the same delay tap values. A frequency domain channel response of each of the channels included in the same group of channels is estimated based on the set of delay tap values estimated for the group.
摘要（中）：
多个无线信道链接发射机和接收机，每个信道对应于不同的发射 - 接收天线对。 通过将多个信道分组成一个或多个组来估计多个无线信道的信道状态信息，每个组包括与两个或多个并置的发射和/或接收天线相关联的信道。 在每个通道组的时域中迭代地估计一组延迟抽头值，使得包括在同一组中的信道与相同的延迟抽头值相关联。 基于针对组估计的延迟抽头值的集合来估计包括在同一组信道组中的每个信道的频域信道响应。
