    • The invention relates to a method which includes, for each group of a set of groups of transmitter/receiver pairs (Ck): the pairs of the group executing an iterative technique of interference alignment during II iterations on signals transmitted by the group; each transmitter (Ek) of the group consecutively sending a drive signal pre-coded by a matrix resulting from said execution; each receiver (Rk) assessing the group of a metric representing a distance between a vector subspace generated by the drive signal with which said receiver forms a pair and a vector subspace generated by interferences determined according to drive signals transmitted by the other transmitters; a central processing unit (UC) calculating an overall metric for each group in accordance with the metrics of the receivers of the group; and the central processing unit selecting one group from among the assembly that optimises the overall metric.

    • Method and arrangement for determining at least one phase affecting error related to transmission from at least one pair of correlated antennas. The method involves transmitting (1002) reference signals from the correlated antennas in the at least one pair, in a set of frequency bands, wherein a number of controlled phase differences are introduced between reference signals transmitted from the antennas. The method further involves receiving (1004), in response to the transmitted reference signals, for a number of the controlled phase differences, one or more indications of a selected precoder matrix. Further, the method involves identifying (1006) changes of selected precoder matrix over the number of controlled phase differences, over the set of frequency bands, wherein the identifying is based on the received one or more indications; and determining (1008) at least one relation between the identified changes. Further, at least one phase affecting: error is determined based on said at least one relation. The method and arrangement enable adjustment of transmission from the at leastone pair of correlated antennas, such that said at least one phase affecting error is reduced.
    • 用于确定与至少一对相关天线的传输相关的至少一个相位误差的方法和装置。 该方法涉及在一组频带中从至少一对中的相关天线发送(1002)参考信号,其中在从天线发送的参考信号之间引入多个受控相位差。 该方法还包括响应于所传输的参考信号,接收(1004)多个受控相位差,所选择的预编码器矩阵的一个或多个指示。 此外,该方法包括在所述频带集合上识别(1006)所选择的预编码器矩阵在受控相位差的数量上的改变,其中所述识别基于所接收的一个或多个指示; 以及确定(1008)所识别的改变之间的至少一个关系。 此外,基于所述至少一个关系确定影响:错误的至少一个相位。 该方法和装置使得能够调整来自至少一对相关天线的传输,使得减少所述至少一个相位影响误差。
