Stability analysis of digital radio channels under the influence of the signal inter-symbolic interference

Abstract

Inter-symbolic interference is analyzed as a disturbance. At a given information flow and known pulse characteristics of the channel, the received signal could be defined with precision up to the additive disturbance. A mathematical model of a radio channel with frequency-dependent parameters received under inter-symbolic interference is proposed. This method for compensation of inter-symbolic interference allows evaluation of the error probability during the process of received signal recognition for different types of signal modulation and proposes algorithms for inter-symbolic interference compensation.
