摘要
A method for providing transmit symbols to be transmitted by a transmitter to one or more receivers of a wireless MIMO communication system is described. The method includes receiving data to be transmitted to the one or more receivers, and obtaining the transmit symbols to be transmitted by multiplying a data vector including the data to be transmitted by a matrix, like a precoding matrix. The matrix is approximated by a plurality of matrices whose elements are positive or negative integer powers of two so that multiplying the data vector by the matrix includes a series of sub-multiplications, each of the sub-multiplications being realized only by bit shifts and additions.
