DEVICE FOR SIGNAL RESOLUTION ON RANDOM NOISE BACKGROUND Russian patent published in 2005 - IPC

FIELD: electrical communications; radio-controlled signal receivers, radar stations, mobile-object communication systems.

SUBSTANCE: proposed device for signal resolution on random noise background has signal processing channels l₁ - l_n, number of signal processing channels being equal to number of resolved-signal superposition combinations; clock generator 2; and comparison unit 3; each signal processing channel has signal correlation processing unit 4 and adder units 5₀ - 5_L, unit 6 for calculating summary likelihood ratio functional of current resolved-signal superposition combination, unit 7 for calculating a posterior probabilities of number combinations of resolved-signal Gaussian components, and extrapolation unit 8. Parallel-conveyer method is implemented in device for processing arriving signal including recursive calculation of likelihood ratio functional which ensures its uncriticality to noise parameters and high signal processing speed.

EFFECT: enhanced reliability of reception in the environment of variable-parameter and structural noise, and echo signals.
