Abstract: PURPOSE: An iterative decoding method and a device thereof are provided to use a function for ordering and cancelling interference, thereby enhancing decoder performance. CONSTITUTION: An LLR calculating unit calculates a channel log-likelihood ratio about a fixed input signal. A deinterleaver(420_1~420_M) de-interleaves a channel log-likelihood ratio value outputted from the LLR calculating unit. A decoding unit(430) iteratively decodes the calculated LLR value to estimate data which is transmitted from a source node. An interleaver(440_1~440_M) changes the input order of an input information bit. An update unit(450) updates an LLR value which is calculated by the LLR calculating unit.
Abstract translation: 目的：提供迭代解码方法及其装置，以便使用排序和消除干扰的功能，从而提高解码器性能。 构成：LLR计算单元计算关于固定输入信号的信道对数似然比。 解交织器（420_1〜420_M）对从LLR计算单元输出的信道对数似然比值进行解交织。 解码单元（430）迭代地解码所计算的LLR值以估计从源节点发送的数据。 交织器（440_1〜440_M）改变输入信息比特的输入顺序。 更新单元（450）更新由LLR计算单元计算的LLR值。

Abstract: PURPOSE: A communication method of a relay network is provided to show high reliability and performance in the relay network. CONSTITUTION: A relay network comprises a source node, a first relay node, a second relay node, and a destination node. The source node broadcasts a polarized information orthogonal frequency division multiplexing (OFDM) block to each of the first node and the second node (S410). The first relay node processes the broadcasted OFDM block (S420). The second relay node processes the broadcasted OFDM block (S430). The first relay node transmits the processed OFDM block to the destination node (S440). The second relay node transmits the processed OFDM block to the destination node (S450). [Reference numerals] (AA) Start; (BB) End; (S410) Source node broadcasts a polarized information orthogonal frequency division multiplexing (OFDM) block to each of the first node and the second node; (S420) Relay node processes the broadcasted OFDM block; (S430) Second relay node processes the broadcasted OFDM block; (S440) Relay node transmits the processed OFDM block to the destination node; (S450) Second relay node transmits the processed OFDM block to the destination node; (S460) Destination node decodes OFDM blocks received from first and second relay nodes; (S470) OFDM blocks decoded from destination node decodes are depolarized
