    • PURPOSE: An apparatus and a method for encoding a low density parity check code are provided to generate a low density parity code having a low error by performing encoding of the low density parity code. CONSTITUTION: A parity check matrix generating part(310) generates a parity check matrix including a parity sub matrix. The parity check matrix includes a matrix element which is a message bit and a matrix element which is a parity bit. A puncturing part(320) performs puncturing about at least one matrix element among matrix element of a parity sub matrix. The puncturing part performs puncturing about at least one matrix element among matrix element of a first block matrix according to a puncturing order. The puncturing part punctures the matrix element of the first block matrix based on a matrix size of the first block matrix in a puncturing process. An encoding part(330) encodes an information word inputted from user by using the parity check matrix.

    • Disclosed is a multi-input multi-output communications method in a large-scale antenna system. An MIMO transmission method includes a step of obtaining channel information on a terminal, a step of dividing the terminal into a class and a group subject to the class, based on the channel information, a step of deciding a group beam forming matrix with the group, a step of performing the group beam forming transmission on terminals included in the group based on the group beam forming matrix, a step of obtaining single Su-CQI information and interference signal information with regard to the terminals included in the group, a step of scheduling the terminals based on the Su-CQI information and interference signal information, and a step of transmitting data to the terminals based on the scheduling. Therefore, the amount of the feedback of the channel condition information can be reduced.

    • A cooperation communication method and a system using feedback signal are provided to perform packet transmission and a relay with a terminal by using a feedback signal of a base station. In a cooperation communication method and a system using feedback signal, a base station(100) mixes a packet transmitted from a first terminal(110-1) and a second terminal(110-2). A first terminal transmits the packet to the base station, and a second terminal retransmits the packet instead of the first terminal when the packet transmitted from the first terminal is fail. The base station includes a transmission unit transmitting the packet to a plurality of terminal(110-1-110-n) and a determination determining whether the transmitted packet is fail or not.
