    摘要: A data transmission method using spatial multiplexing is disclosed. The data transmission method using spatial multiplexing includes modulating at least one codeword to generate at least one modulation symbol, mapping the at least one modulation symbol to a layer whose number is determined according to its rank to generate a layer-mapped symbol stream, performing discrete Fourier transform (DFT) on the layer-mapped symbol stream to generate a frequency domain symbol stream, performing precoding on the frequency domain symbol stream, mapping the precoded frequency domain symbol stream to subcarriers, and then performing inverse fast Fourier transform (IFFT) on the precoded frequency domain symbol stream-mapped subcarriers to generate SC-FDMA symbols; and transmitting the SC-FDMA symbols by using a plurality of transmission antennas. Spatial multiplexing having a low PAPR can be possibly performed in an SC-FDMA system.
