FIELD: communication.
SUBSTANCE: invention relates to the field of multichannel communication. Proposed is a method for non-orthogonal multiple access based on partial encoding, wherein the signal for each of the N parallel channels is subjected to a reverse fast Fourier transform, digital-to-analogue conversion with combination of the signals, carrier modulation, and at reception: the signal is subjected to carrier demodulation, analogue-to-digital conversion with division of the signals into N parallel channels, fast Fourier transform, wherein at transmission: the signal for each of the N parallel channels is subjected to a pre-coding procedure modulo two: mod 2, depending on the channel number and defined as: b(k)=a(k) ⊕ b(k-in), wherein: a(k) is a binary signal at the input of the precoder, b(k) is a binary signal at the output of the precoder, in=1, 2, 4, …, and n=1, 2…Ν; the signal for each of the N parallel channels is subjected to partial encoding, i.e. digital filtering, by a filter with a finite pulse response depending on the channel number and defined as: c(k)=b(k)-b(k-in), wherein: c(k) is the symbol at the output of the encoder, in=1, 2, 4, …, and at reception: the signals from N parallel channels, excluding the 1st channel, are subjected to consecutive suppression of the mutual influence accounting for the weighting coefficients defined as bn(mn)=sin2(in*π/m n), wherein mn=2*i n; the signal from each of the N parallel channels is decoded, wherein "1" and "-1" are decoded as "1", and "0" is decoded as "0".
EFFECT: efficient use of the frequency spectrum and reduction in the computational costs when implementing the algorithm for consecutive suppression of mutual influence compared to the Power Division - Non-Orthogonal Multiple Access method.
