Abstract :
In this article the method of demodulating of non-orthogonal N-OFDM signals, that are formed by Hartley transform, is described. N-OFDM demodulation was based on the assessment of accepted amplitudes by Cauchy method, by solving a system of linear algebraic equations. In addition, the article consider the possibility of increasing the spectral efficiency of the system due to compression of N-OFDM, and system´s interference immunity by introducing algorithm of demodulation threshold device.
