FIELD: information technology.
SUBSTANCE: multiple streams of encoded data are generated, a symbol sequence is generated from each stream of encoded data based on the selected modulation scheme, Fourier transformation is performed on each symbol sequence to generate frequency domain data, one of types of encoding or spatial multiplexing on frequency domain data based on channel status information is selectively performed, symbols in each of the symbol sequence are displayed on subcarriers, inverse Fourier transformation is performed and time domain data are transmitted.
EFFECT: higher data transmission speed and transmission capacity.
