Abstract:
1. A method for transmitting a plurality of data symbols using a plurality of transmit antennas and a plurality of transmission resources comprising: generating a plurality of transmission symbols from the plurality of data symbols; and associating each transmission symbol with one of the plurality of transmit antennas and one of the plurality of transmission resources; wherein the transmission symbols are generated and associated with the transmit antennas and transmission resources such that the transmission symbols are written in the form of a first matrix with a sub-vector in a first dimension for each of the plurality of antennas and a sub-vector in a second dimension for each of the plurality of the transmission resources, such that each component of the matrix holds the transmission symbol that is transmitted using the antenna corresponding to sub-vector in the first dimension in which the component is positioned and using the transmission resource corresponding to the sub-vector in the second dimension in which the component is positioned, and the first matrix is represented as a combination of a second matrix and a third matrix, and wherein for each of the second matrix and the third matrix, each component of the matrix is equal to one of the data symbols or the complex conjugate of a data symbol to be transmitted multiplied by a weighting factor and the matrix is divisible into sub-matrices of dimension at least 2×2 such that, for each two sub-matrices having only column sub-vectors of the same columns or row sub-vectors of the same rows, at least one component of one of the two sub-matrices differs from the corresponding component of the other of the two sub-matrices at least in the phase or the absolute value of the weighting factor.
