TRANSMITTING AND RECEIVING METHOD OF DISCRETE INFORMATION IN RADIO LINE WITH PSEUDO-RANDOM TUNING OF OPERATING FREQUENCY Russian patent published in 2010 - IPC H04B7/00 

FIELD: radio engineering.

SUBSTANCE: N-fold repetition of each information bit occurs on transmitting end of radio line, where N≥3, in K frequency positions, and transmitted radio signal is received on receiving end of radio line, probability of error of signal reception of p_er1 bit is calculated, values of single received bits are ranged in compliance with their error probabilities, then all ranged M-sequences of single received bits, where M=N, M=N-2,…, M=3, are decoded at one and the same time as per majority circuit and error probability of p_er(M) is calculated for each M value, obtained p_er(M) values are compared to each other and final decision is taken on the value of transmitted bit, which corresponds to minimum p_er(M) value.

EFFECT: increasing interference immunity of received discrete information.
