The work is devoted to the study of the features of the functioning of radio engineering data transmission systems in the presence of intersymbol interference in linear radio paths in the presence of detuning caused by transient processes on the output of linear selective systems under action of multi-position phase-manipulated signals with n discrete states.
The effect of the initial phase shift of the signal constellation of a multiposition phase-shift signal with n discrete states on the error probability during its reception and processing under conditions of strong ISI arising due to transient processes occurring in the linear radio path of the radio engineering data transmission system is investigated. The initial phase shift of the signal constellation is de-termined, in which there is no constant error when receiving and processing the signal under ISI. The possibility of increasing the symbol transmission rate in bandpass filters is shown.
