Abstract: PURPOSE: A high order modulation demapping communication method is provided to offer an optimum bit separation method for demodulating 8PSK, 16APSK and 32 APSK modulation signals. CONSTITUTION: A high order modulation demapping communication method applying an adaptive modulation method in marine time communication includes a stage of applying an approximate formula omitting a logarithmic calculation process and an exponential process in an LLR(Log Likelihood Ratio) method and a stage of determining a reception bit by calculating a distance between a reception signal and a mapping point of a constellation after omitting a multiplication part multiplying a channel estimation value in an approximate formula.

Abstract: PURPOSE: A LDPC(Low Density Parity Check) decoding method is provided to decrease a repeating time for an error correction to less than half times by decreasing a degradation and decrease the computational amount for the error correction, thereby reduce the power consumption. CONSTITUTION: A decoding method of a low complexity LDPC decoding device comprised of a bit to check block and a check to bit block includes followings: a decoding step performing decoding by dividing a check node and a bit node into a specific number of decoding module in order to reduce a repeating time without the performance loss, and using a sequential decoding algorithm which delivers the decoded check node and the bit node to the next decoding module; and a decoding step using an early-stop algorithm which ends the decoding by the repeating if the two decoding bit is same when comparing a decoding bit determined by the repetition and the decoding bit determined by the previous repetition.

Abstract: PURPOSE: A flow mobility supporting method of a multi-interface terminal in a PMIPv6 environment is provided to successfully transmit packets in which flows are moved to an MN(Mobile Node) by confirming the connection of the multi-interface terminal. CONSTITUTION: When an MAG2(Mobile Access Gateway2) senses the connection of an MN through an IF2(Interface2), the MAG2 transmits a PBU(Proxy Binding Update) message to an LMA(Local Mobility Anchor). The LMA determines the connection of the MN by using an MN recognition interface and by comparing the data of BCE(Binding Cache Entry) with an ML-ID(Identification). When the MN is connected, the LMA shares HNP(Home Network Prefix) between the MAG1 and the MAG2.

Abstract translation: 目的：提供一种PMIPv6环境中多接口终端的流动移动支持方法，通过确认多接口终端的连接，成功发送流向MN（移动节点）移动的分组。 构成：当MAG2（移动接入网关2）通过IF2（接口2）感测到MN的连接时，MAG2向LMA（本地移动锚）发送PBU（代理绑定更新）消息。 LMA通过使用MN识别接口并通过比较BCE（绑定缓存条目）的数据与ML-ID（识别）来确定MN的连接。 当MN连接时，LMA在MAG1和MAG2之间共享HNP（家庭网络前缀）。
