Abstract
Methods and devices for removing cross coupling effects between elements of an antenna array () are provided. Cross coupling coefficients between all pairs of antenna elements of the antenna array are predetermined to minimize a total power in theoretical null points calculated without considering the cross element effects. A transceiver () includes a multiplexing block () configured to receive data signals to be transmitted via the antenna elements and to output to at least one of the antenna elements, a sum signal including (i) a data signal, which data signal is designated for the at least one antenna element, and (ii) a linear combination of data signals designated for other antenna elements of the antenna array, each of the data signals in the linear combination being weighted by a respective cross coupling coefficient between the at least one antenna element and an antenna element emitting the each of the data signals.
