Various embodiments are disclosed for the transmission, reception, and a system using multiple antennas. In one embodiment, the transmission apparatus includes a first transmission signal generator for generating a first transmit signal to be transmitted by receiving the first data over a plurality of the first transmission antenna; And it may include a second input for receiving a plurality of data of the parts of the second transmission signal generator for generating a second transmission signal to be transmitted through the second transmit antenna. A first transmission signal to each of the plurality of first coded symbol columns - the first created by applying a multi-antenna transmission coding for the first data, each of contain the symbol stream of the signal component, the second transmission signal includes a plurality of second encoding symbol columns may include the symbol stream of the signal components generated by applying a multi-antenna transmission for encoding the second data. A first transmission signal and the second transmit signals are transmitted using the same communication resources at the same time, the power average of the first encoding symbol column signal components included in each of the first transmission signal is included in each of the second transmission signal the power may be greater than the average of the 2 coded symbols column signal component.
