In the case of electric field influence BER increases from 2.13T0-14 to 6.66T0-12 for amplitude modulation using NRZ code and from 7.58-10-28 to 1.64-10-24 for POLSK modulation.
It is approximately [10.sup.-17] in NRZ - DPSK case, about [10.sup.-25] in NRZ--OOK and [10.sup.-40] in 2 POLSK. Reducing channel spacing to 37.5 GHz, become evident special features of combined transmission and they stand out even more against the background, if 25 GHz interval is used for channel separation.
