Abstract:
A transmission apparatus includes a layer mapper to map a modulated symbol to a plurality of layers, a layer shifter to uniformly divide the symbol mapped to each of the plurality of layers, in a plurality of time domain streams, and a signal transmission unit to perform a DFT on each of the plurality of time domain streams to generate a plurality of frequency domain streams, and to transmit, to a receiving apparatus. The plurality of frequency domain streams are using a plurality of antennas corresponding to each of the plurality of frequency domain streams.
