METHOD FOR PREPARING THE TRANSMISSION OF SIGNALS FOR ETHERAL DIGITAL TV AND BROADCASTING IN ADJACENT CHANNELS

摘要

A method for preparing the transmission of digital terrestrial television broadcasting programs in adjacent channels, namely, that digital television broadcasting signals with different powers and given spectral characteristics are added and broadcast, characterized in that the powers of the summed signals are adjusted so that their difference before summing is not exceeded 20 dB, measure the effective radiated power of digital television broadcasting signals in adjacent channels, determine their difference, adjust the signal power digital television broadcasting so that the difference between the effective radiated powers in adjacent channels does not exceed 20 dB.
