Abstract :
The results of theoretical and experimental investigations of signal transmission COFDM by means of radio-relay line with the use of apparatus “Evrika” in the frequency range 12,75 - 13,25 GHz are presented. It has been proved that transmission rate increased in 2 times, communication range in 2-4 times in comparison with RRL with QPSK modulation due to higher energetic and spectral characteristics of RRL with OFDM.
