In article the method of non-orthogonal frequency division multiplexing (N-OFDM) on the basic of the Hartley transform with quadrature amplitude modulation (QAM) of the frequency carriers is considered. Application of a real kernel of functions Hartley provides calculations without use of complex numbers and, as consequence, allows to reduce computing expenses, to simplify hardware realisation of method N-OFDM. Modulation of separate frequency carriers signals N-OFDM with use of QAM modulation raises throughput of communication channels.
