METHOD FOR RECEIVING SIGNALS WITH TURBO-ENCODING ON BASIS OF CONVOLUTION CODES WITH ELEMENT-WISE DECISION-MAKING ACCORDING TO ALGORITHM OF MAXIMUM A POSTERIORI PROBABILITY

摘要

FIELD: communication systems which use signals with turbo-encoding on basis of convolution codes, namely, methods for iterative receipt of signals with turbo-encoding.;SUBSTANCE: in accordance to the method, received series is decoded according to algorithm of maximum a posteriori probability, soft solutions of informational and check bits are normalized, solved code words are generated at given length of decision-making, scalar result of multiplication of normalized series and generated code words is computed, most probable code word is selected on basis of maximum scalar result of multiplication, scalar result of multiplication is compared to boundary of existence of single code word, informational bits are extracted and rigid decision is made.;EFFECT: reduced probability of errors per block of turbo-code, resulting in increased trustworthiness of receipt of turbo-encoded signals.;5 cl, 2 dwg
