In the paper, operation algorithms of the N-OFDM modem for channels with the Additive White Gaussian Noise (AWGN) are considered. The algorithms are based on the Hartley transform under the optimal demodulation by the estimation of the received signals amplitudes using the Cauchy method. The experimental results for interference immunity estimation are provided for different values of spacing frequencies...
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...
In the paper, research results of the distortion effect of an N-OFDM signal are presented. The consequence emerges due to a frequency drift of the carrier wave because of the Doppler effect during user's movement and instability of oscillator frequency, when a transfer of the spectrum is implemented in transmitting and reception path of the communication system. The N-OFDM signal based on the Hartley...
