Various embodiments are disclosed for the transmission, reception, and a system using multiple antennas. In one embodiment, the receiving apparatus receives a radio signal through at least one receive antenna for receiving an output of at least one of a received signal; And it may comprise a symbol detector for detecting the first and second symbol streams based on the at least one received signal. The wireless signal may include a second transmission signal to be transmitted through the first transmit signals and the second plurality of transmission antennas to be transmitted over a plurality of the first transmission antenna. A first transmission signal to each of the plurality of first coded symbol columns - first created by applying a multi-antenna transmission coding for the data-in is a plurality of containing the symbol stream in the signal component, each of the second transmission signal The 2 coded symbols columns - created by applying a multi-antenna transmission for encoding the second data may include the symbol stream of the signal component. The first and the second transmission signal and the transmission signal are transmitted by 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 second may be larger than the average power of the second encoding symbol column signal component.
