Abstract

The paper considers a data transmission method in radio relay communication systems based on the use of nonorthogonal frequency discrete modulation (N-OFDM) of signals in combination with their orthogonal polarization. Synthesis of demodulation procedure of N-OFDM signals is conducted with regard for the presence of cross-polarization interference. In order to analyze the potentialities of the procedure synthesized, it is proposed to employ the well-known procedure of calculating the Cramer-Rao lower bound for variance of potentially achievable errors at measurement of quadrature components of signal amplitudes.
