Abstract:
1. A method for transmitting signals in a system using a plurality of antennas, the method comprising: multi-antenna-encoding a plurality of data symbols to form a plurality of transmitting symbol groups each of which corresponds to an antenna among the plurality of antennas and has a plurality of transmitting symbols generated from the plurality of data symbols; and transmitting each of the plurality of transmitting symbol groups through a corresponding antenna among the plurality of antennas using a group of time-frequency resources, wherein at least two antennas among the plurality of antennas transmit transmitting symbols generated from a same data symbol on a same time-frequency resource in the group of time-frequency resources, wherein a number of the plurality of antennas is 4, and transmitting symbols transmitted through each of the 4 antennas using two time-frequency resources in the group of time-frequency resources are represented by a first matrix as follows: wherein each row of the first matrix represents a time-frequency resource and each column of the first matrix represents an antenna, and each element of the first matrix represents a transmitting symbol transmitted through i-th antenna (i=1, 2, 3, 4) using j-th time-frequency resource (j=1, 2), where s
