TRANSMISSION, RECEPTION AND SYSTEM USING MULTIPLE ANTENNAS

摘要

Various embodiments of a transmission, a reception, and a system using multiple antennas are disclosed. According to an embodiment of the present invention, a transmission apparatus can comprise: a first transmission signal generation unit which receives first data and generates first transmission signals to be transmitted through a plurality of first transmission antennas; and a second transmission signal generation unit which receives second data and generates second transmission signals to be transmitted through a plurality of second transmission antennas. The each first transmission signal can include a relevant symbol stream among a plurality of first encoding symbol streams as a signal component. The plurality of first encoding symbol streams are generated by applying an encoding for a multiple antennas transmission to the first data. The each second transmission signal can include a relevant symbol stream among a plurality of second encoding symbol streams as the signal component. The plurality of second encoding symbol streams are generated by applying the encoding for the multi antenna transmission to the second data. The first transmission signals and the second transmission signals are transmitted at the same time by using same communications resources. An average power of the signal component of the first encoding symbol streams included in each of the first transmission signal may be greater than an average power of the signal component of the second encoding symbol streams included in each of the second transmission signals.
