The non-orthogonal frequency division multiplexing (N-OFDM) signals
Part 1

The article consists of two parts. FDM theoretical propositions and the possibility of the improvement of the efficiency of the spectral system by using N-OFDM (Non-Orthogonal Frequency Division Multiplexing which is based on the FDM principles) are seen in the first part of the article. The problems of N-OFDM realization and ways of its solution are analyzed. The algorithm of demodulation of the N-OFDM signals is described.
