    • The present invention relates to a decoding device and method for a MIMO system. A linear process is applied to a received signal vector by using a channel matrix estimated from the received signal vector and a poly-diagonalized matrix, and a soft decision value is acquired through a trellis decode by using the linear process result. Since the linear preprocess is performed by using the poly-diagonalized matrix, it is possible to receive a MIMO signal having good packet error rate performance and less complexity. Also, since the tail-biting trellis decoding method is used based on the poly-diagonalized matrix that is generated by poly-diagonalizing the effective channel matrix during the process for eliminating the signal interference, the soft decision value for the symbol can be generated with a simple hardwired device and less operation complexity.
    • 本发明涉及MIMO系统的解码装置和方法。 通过使用从接收信号向量和多对角化矩阵估计的信道矩阵将线性处理应用于接收信号向量,并且通过使用线性处理结果通过网格解码获取软判决值。 由于通过使用多对角化矩阵来执行线性预处理,所以可以接收具有良好的分组错误率性能和较低复杂度的MIMO信号。 另外,由于基于在消除信号干扰的处理期间通过对有效信道矩阵进行多对角化而产生的多对角化矩阵使用尾巴格状解码方法,所以可以生成符号的软判决值, 简单的硬连线设备,操作复杂度较低。
