FIELD: radio engineering, communication.SUBSTANCE: transmitter includes multiple transmitting antennae; a conversion unit configured to generate multiple signal sequences corresponding to a predefined frequency bandwidth from one or more transmission streams associated with any of the transmitting antennae; a precoding unit configured to set the weight the signal sequences using a precoding matrix selected from a code module including multiple predefined precoding matrices; and a transmitting unit configured to convert an output signal from the precoding unit into a number of signals corresponding to the number of transmitting antennae and transmit the converted signals from the transmitting antennae. The precoding unit applies different precoding matrices to different signal sequences, and the relationship between the different precoding matrices and the different signal sequences is determined through open-loop control which is independent of feedback from a receiver.EFFECT: high capacity.24 cl, 18 dwg |
