摘要 VBLAST是一种用于MIMOO FDM系统的有效检测方法,但具有较大的计算复杂度。文中基于QR分解检测算法,提出了一种改进的SDQR分解算法。将该算法与常规VBLAST检测算法在相关Rayleigh信道下进行性能仿真实验,结果表明,采用改进的SDQR方法取得了比基于QR分解检测算法更好的误码性能。 VBLAST is an effective detection method for MIMO OFDM systems, but has a large computational complexity. Based on correlation channel conditions, this paper proposes an improved QR signal detection, and its performance is also analyzed.
