摘要：
A codebook generation method for a multi-polarized MIMO(Multi Input Multi Output) system and a device therefore are provided to generate a precoding matrix when antennas have multi-polarization by using a single-polarized precoding matrix, thereby generating a high-performance precoding matrix even by simpler operation. A single-polarized precoding matrix is assigned to diagonal blocks of plural blocks divided according to the number of polarized directions of transmission antennas(S210). A zero matrix is assigned to the rest of the blocks except the diagonal blocks(S220). A precoding matrix is generated by combining the zero matrix assigned to the rest of the blocks with the single-polarized precoding matrix assigned to the diagonal blocks(S230). The precoding matrix is reconfigured by selecting at least one column vector included in the precoding matrix according to transmission ranks corresponding to the number of data streams to be transmitted(S240-S260).
摘要（中）：
因此，提供了一种用于多极化MIMO（多输入多输出）系统的码本生成方法和一种装置，用于通过使用单极化预编码矩阵来产生天线具有多极化的预编码矩阵，由此产生高性能预编码 矩阵甚至通过更简单的操作。 将单极化预编码矩阵分配给根据发送天线的偏振方向的数量分割的多个块的对角块（S210）。 零矩阵被分配给除对角块之外的其余块（S220）。 通过将分配给其余块的零矩阵与分配给对角线块的单极化预编码矩阵组合来生成预编码矩阵（S230）。 通过根据与要发送的数据流的数量相对应的传输级别选择预编码矩阵中包括的至少一列列向量来重新配置预编码矩阵（S240-S260）。
