MULTIPLE-INPUT MULTIPLE-OUTPUT-ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM, TRANSMISSION APPARATUS, RECEPTION APPARATUS, AND TRANSMISSION AND RECEPTION METHOD CAPABLE OF PROMOTING DIVERSITY GAINS BY USING CHANNEL STATE INFORMATION

摘要

PURPOSE: An MIMO(multiple-input multiple-output)-OFDM(orthogonal frequency division multiplexing) system, transmission apparatus, reception apparatus, and transmission and reception method are provided to obtain promoted signal space diversity gains by using size information of channel state information.;CONSTITUTION: Coordinate rotary units(103-1~103-t) individually rotates coordinates of complex symbols. Interleavers(105-1~105-t) are interleaved into the rotated symbols. Two sub-carriers are selected from the rotate symbols. A real part or an imaginary part of selected sub-carriers is exchanged. Time area conversion units(107-107t) converts the interleaved symbols into the time area signal.;COPYRIGHT KIPO 2013;[Reference numerals] (101-1,101-2,101-t) Mapping unit; (103-1,103-2,103-t) Coordinate rotary unit; (105-1,105-2,105-t) Interleaver; (107-1,107-2,107-t) Time area conversion unit
