    Abstract: PURPOSE: A high speed decoding method for a low-density parity-check code is provided to obtain low error floor, by using BPSK(Binary Phase Shift Keying) modulation and additive white Gaussian noise channel environment. CONSTITUTION: An LDPC(Low Density Parity Check) code is decoded by LDPC decoding method using a message expressed as an LLR value. The message is converted into a bit stream corresponding to the LLR value. The LDPC code includes a variable node updating procedure using a bit stream. The variable node updating procedure includes a binary calculation procedure among input message values. The variable node updating procedure uses a threshold value.

    Abstract translation: 目的:通过使用BPSK(二进制相移键控)调制和加性白高斯噪声信道环境,提供了一种用于低密度奇偶校验码的高速解码方法,以获得低误码大小。 构成:通过使用表示为LLR值的消息的LDPC解码方法对LDPC(低密度奇偶校验)码进行解码。 该消息被转换成与LLR值对应的比特流。 LDPC码包括使用比特流的可变节点更新过程。 变量节点更新过程包括输入消息值之间的二进制计算过程。 变量节点更新过程使用阈值。
