DIGITAL INFORMATION RECEPTION METHOD WITH THE PRESENCE OF INTERSYMBOL INTERFERENCE Russian patent published in 2018 - IPC H04L12/00 

FIELD: data processing.

SUBSTANCE: invention relates to the field of digital information transmission. Method comprises the following operations: to each possible i-th hypothesis of the received message DS sequence forming the corresponding to these hypotheses the accompanying q_{ir accomp}(t) the PI component implementations; at each TTI r-th cycle, performing the s_r(t) signal implementation compensation observed on this cycle, each of all the above-mentioned IP components implementations formation results combinations in accordance with ratio δ(t)_ir=s_r(t)-q_{ir accomp}(t); calculating each of the compensation result energy n_ir in accordance with ratio ; calculate the PC ξ_ir total correlation statistics between the signal and each i-th set of functions; at each TTI r-th cycle of each i-th PC z_ir is calculated taking into account the total correlation PC ξ_ir and energy n_ir; decision on the received DS sequence at each TTI r-th cycle of is made by selection of the maximum of the decisive statistics (PC) z_ir, worked out on this cycle from all possible DS sequence hypotheses.

EFFECT: technical result is increase in the digital information reception noise immunity.
