FIELD: information technology.
SUBSTANCE: invention relates to the field of digital information transmission and can be used in receiving devices of synchronous digital communication systems operating, in particular, in conditions of multipath propagation. Method contains the steps of: at each r-th cycle of the time interval for receiving a message (TIRM), the decisive statistics (DS) are calculated ξirk as a correlation between the signal, observed on the r cycle of the TIRM, and each ik set of support functions, on each r cycle of the TIRM with each k separately form the first and second groups of PC ξirk, at each r cycle of the TIRM, two groups of sums of ranks are formed; at each r cycle of the TIRM, according to the results of the specified operation of summation of ranks PC, the expected sequences of alternatives to the elementary parcel (EP) are determined, for each i of the hypothesized hypotheses, the sequence of EPs received at each r cycle of the TIRM form realizations accompanying these hypotheses that accompany the components of interference noise (IN), at each r cycle of the TIRM, compensation is made in the realization of the signal observed during this cycle of each of the combinations of the results of the formation of the implementations of the mentioned components calculate the energy of each result of the specified compensation, the decision on the accepted sequence of EPs at each r cycle of the TIRM is taken by comparison between the final PCs generated at this clock cycle using the energy calculation results.
EFFECT: technical result is a reduction in computing resources.
