空时旋转不变性编码技术及其频率选择性信道盲估计方法

Space-Time Rotational-Invariance Coding Technique and Corresponding Blind Estimation Scheme of Frequency-Selective Channels

  • 摘要: 针对处于频率选择性衰落环境中的垂直型贝尔实验室分层空时(Vertical Bell iabs LAyered Space-Time,V-BLAST)结构,该文首先对其进行联合空时符号分组,然后提出了一种新颖的空时旋转不变性编码技术(Space-Time Rotational-Invariance Coding Technique,STRICT)。通过巧妙利用上述编码技术中的旋转不变性性质,该文继续为V-BLAST结构提出了一种多输入多输出(Multiple-Input Multiple-Output,MIMO)频率选择性无线信道的盲估计方法。仿真结果表明了该文新颖STRICT的有效性及其信道盲估计方法的性能。
