FIELD: information technology.
SUBSTANCE: disclosed is a signal transmitting device comprising: a forward error correction (FEC) encoder which performs FEC coding of input data according to a Bose-Chaudhuri-Hocquenghem (BCH) coding scheme and a low-density parity check (LDPC) coding scheme; a first interleaver which interleaves FEC coded data; a symbol display unit which converts the interleaved data into data symbols; a second interleaver which interleaves data symbols; an encoder which codes data symbols interleaved by the second interleaver according to a multiple-input single-output (MISO) coding technique; a unit for inserting a pilot symbol into data frames which contains coded data symbols. At least the pilot symbol includes information for the type of transmission according to the MISO coding technique; and a transmitter for transmitting the data frame which includes the pilot symbol and data symbols.
EFFECT: high efficiency o using channel bandwidth, high rate of transmitting data and longer signal transmission distance.
