METHOD FOR DETERMINATION OF WEIGHT CHARACTERISTICS OF VALIDITY FOR PROCESSING OF RECEIVED MULTIWAY SIGNALS Russian patent published in 2008 - IPC H04B7/04 

FIELD: physics, radio.

SUBSTANCE: invention is related to radio communication and may be used in reception of diverse digital signals by telemetering facilities. In n diversion channels m-positional signals are received, which include information and test signals, which are converted into units of elementary data, every of which represents pulse r-discharge signals in parallel binary code accompanied by clock pulses and separated with markers, at that m=2^r, m≥1. In every channel number of matches of r-charge test signals are determined N_{test_valid_i}, i = 1, 2, ..., n, where N_{test_valid_i} - number of matches in i channel. Units of elementary data of every channel are distributed in the order of reduction of number of matches N_{test_valid_n}≥N_{test_test_n-1}≥_...N_{tes_valid_i......}N_{test_valid_2}≥N_{test_valid_1}. Combinations {W_ki} of weight characteristics of validity are calculated (VHD) {W_ki}_n-opt k=1, ..., q, at that W_k1<W_k2<...W_k,i...<W_k,n-1. <W_k,n, where k ^_ number of combination, i - number of channel, and q - number of combinations. Corresponding pulse r-discharge test signals are compared for their identity, and pooled estimates of validity are calculated according to formula e=1, 2, ..., m, where W_ki - VHD of k combination for i channel of diversity, e - value of position in m-positional test signal. Amongst calculated pooled estimates of validity W_ke maximum pooled estimate of validity is determined, as well as corresponding value of position e_ob-test-k. Pooled estimates of validity are calculated for subsequent r-discharge test signals and maximum pooled estimate of validity is calculated, as well as corresponding value of position e_ob-test-k (k=1, 2, ..., q). Values of positions e_ob-test-k (k=1, 2, ..., q) of test signals are compared to their reference values. Number of matches is determined. All above mentioned operations for determination of matches number are repeated for every k combination, and out of them combination k=h is selected with maximum number of matches and corresponding e_ob-test-h and VHD combinations are used that are corresponding to h combination for processing of received m-positional signals. Method makes it possible to increase speed of data processing and noise immunity under conditions of random noises effect.

EFFECT: increase of data processing speed and noise immunity under conditions of random noises effect.
