A numerical method to estimate the potential capacity of communication channels using FSK-N-signals with ISI

© 2020 IEEE. The paper presents the methodological aspects of numerical method to estimate the capacity of channels with memory caused by its frequency selectivity, when frequency shift keyed signal are used. The impact on potential capacity of adverse factors such as measurement errors, which take into account restrictions on the noise reduction system and measurement errors caused by a frequency synthesizer of the transmitter and detector, as well as the effect of the noise reduction system in the receiver, is estimated
