Abstract:
1. A system including: a transmission apparatus comprising: at least two encoding units, each configured to encode a bit stream; at least two interleaving units, each configured to interleave the encoded bit stream; at least two Gray mapping units, each configured to perform Gray mapping for the interleaved bit stream; at least two pilot insertion units, each configured to insert a pilot symbol into the mapped bit stream; and at least two transmit antennas, each configured to transmit the bit stream with the inserted pilot symbol, wherein the transmission apparatus has a horizontal encoding structure and is configured to transmit a different bit stream for each transmit antenna; and a reception apparatus configured to receive at least one of the different bit stream for each transmit antenna transmitted by the transmission apparatus, comprising: a detection unit configured to detect extrinsic information based at least partly on an output of a tentative symbol decision unit associated with the received at least one of the different bit stream for each transmit antenna transmitted by the transmission apparatus; and a decoding unit configured to output an interleaved bit or a posteriori information thereof based on the extrinsic information.
