METHOD FOR SEPARATING SIGNALS UNDER ACTION OF INTRA-SYSTEM INTERFERENCE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC H04B15/00 

FIELD: electricity.

SUBSTANCE: signal separation method under the influence of the intra-system interference is that, over the vector of the input signal mixture sampling and the arbitrary interference U_k in each signal processing channel, correlation processing is carried out for each N Gaussian random process in the form of

the maximum result value of the correlation processing x_i=maxx_in is found on each Gaussian component of the poli-Gaussian decomposition of the total interference, the current combination of the differentiated reference signals is determined according to the rule and for the decision on the reference signal S_i, the conversion is performed in accordance with the decisive rule: where S_i - a reference signal; L - a linear transformation matrix; R - a cross-correlation matrix of the reference signals, included in the linear transformation matrix; σ² - an interference disturbance; A - a diagonal matrix, the elements of which correspond to the energies of the received users signals; - a combination of the correlation processing result values of the preliminary decisions on the signals; c₁ - a threshold.

EFFECT: increasing the signals receiving acuracy under the influence of the intra-system interference.
