Title:
COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/143720
Kind Code:
A1
Abstract:
The conventional MIMO-OFDM transmission has a drawback that the system structure is complicated because different phase rotations are imparted to the respective ones of subcarriers and the respective ones of antennas. There are included a copying means (004) for copying a group, which consists of a predetermined number of subcarriers and a predetermined number of symbols for a data to be transmitted, thereby generating a plurality of groups; phase rotating means (006) for imparting different phase rotations to the respective ones of the plurality of groups as copied; and a plurality of transmission antennas (009) for transmitting, to a receiver, the respective ones of the plurality of groups to which the respective phase rotations have been imparted.
