Interference immunity analysis of an optimal demodulator under peak multiplexing of N-OFDM spectrum

Abstract

In the paper, a method of an optimal N-OFDM signals demodulator is considered. Signals are generated by means of the Hartley transform by the estimation of the received signals amplitudes using the Cauchy method. The experimental data outlined in the paper corresponds to the system interference immunity analysis for different values of spacing frequencies between subcarriers frequencies under the maximum possible multiplexing of N-OFDM signals spectrum with BPSK modulation. The numerical results were obtained by the mathematical modeling in Matlab.
