METHOD TO GENERATE CHANNEL SIGNALS AND DEVICE THAT IMPLEMENTS IT Russian patent published in 2012 - IPC H04J1/20 

FIELD: information technologies.

SUBSTANCE: device that implements the Method to generate channel OFDM signals comprises a source of information, a unit comprising a converter of serial symbols into parallel ones and an expander, a unit to insert a protective interval and a quadrature modulator comprising two digital-to-analog converters, two multipliers, a bearing oscillation generator, a device of phase shift by π/2, a summator, a unit of signal generation on the basis of internal vectors of subband matrices, which includes a generator of internal vectors of subpolar matrices, a device to control the generator of the internal vectors of subband matrices, J multipliers to multiply n arriving parallel information symbols to internal vectors of subpolar matrices and the summator.

EFFECT: increased number of channels simultaneously transferring data in a dedicated frequency range and reduction of interference noise of radio communication systems.
