Abstract
FIELD: radio engineering communication.SUBSTANCE: wireless transmitter includes a plurality of encoding and modulating units for applying corresponding encoding and modulation algorithms to input data units. A discrete Fourier transform (DFT) precoder performs using DFT processing of output data of encoding and modulating units and an inverse fast Fourier transform (IFFT) unit receives the DFT output signal from the DFT precoder which is projected on different subcarriers in accordance with allocation of resources indicated by a base station and also performs through IFFT processing of the output signal processed through DFT. The output data processing step generates output signals based on the output signal of the IFFT unit for wireless transmission thereof to a wireless receiver. In various versions of the invention output data of the encoding and modulating units may be transmitted to an IFFT unit to generate output information processed through IFFT.EFFECT: high transmission channel capacity.19 cl 4 dwg
