APPARATUS AND METHOD OF TRANSMITTING/RECEIVING SIGNALS USING SIGNALING POINT ROTATION AT MUTUAL COOPERATION TRANSMISSION

摘要

An apparatus for and method of transmitting and/or receiving a signal by using signaling point rotation in mutually cooperative relaying are provided. The apparatus for transmitting a signal includes: a rotated I-channel generation unit rotating a symbol containing data of a first user, by a predetermined angle, and then, obtaining the I-channel (in-phase) component of the rotated symbol; a rotated Q-channel generation unit receiving a symbol rotated by a predetermined angle, of a previous time slot from a node of a second user performing mutually cooperative relaying with the node of the first user, detecting the I-channel component, and obtaining the Q-channel (quadrature-phase) component of a symbol containing data of the second user from the detected I-channel component; and a combining unit combining the I-channel component of the first user generated in the rotated I-channel generation unit and the Q-channel component of the second user generated in the rotated Q-channel generation unit, thereby generating one symbol.
