METHOD OF ESTIMATION OF ERROR PER BIT PROBABILITY BY RESULTS OF DECODING CODE WORDS Russian patent published in 2018 - IPC H04L1/20 H03M13/01 

FIELD: radio engineering, communication.

SUBSTANCE: method of estimation of error per bit probability, where the message source generates a sequence of bits, and transmits it to the input of the encoder, which uses a linear block code encodes a sequence, receiving a code word with a length of n bits, and then the code word is sent from the output to the input of the modulator, which implements modulation, and an information signal is received. The signal is transmitted to the communication channel, and from the output of the communication channel the signal is sent to the input of the demodulator, in which they receive an adopted code combination which may contain errors due to the presence of the distortion in the communication channel. The code combination is sent to the input of the decoder which decodes the combination and an information word is obtained, as well as the q number of detected errors. From the first output of the decoder the information word is sent to the input of the message receiver input, and from the second output of the decoder the q number is sent to the input of the verification unit. The q number is equal to the number of errors detected by the decoder in the received code word.

EFFECT: increase in the data transmission rate by estimating the probability of error per bit when encoding using a linear block of noise-immune code.
