Abstract

Estimating the channel state information (CSI) of several transmitters that use orthogonal space-time block codes (OSTBC) to communicate with a single receiver is considered. Based on Rank Revealing QR (RRQR) factorization and Propagator method (PM), two new algorithms to estimate multiuser MIMO channels are proposed. The algorithm estimates the subspace spanned by the user channels use only a few training blocks to extract the users CSI from this subspace. Our both algorithms achieve better performance in comparison with reference LS based approach. Computer simulations are included to validate proposed methods.
基于PM和RRQR方法的半盲多用户MIMO信道估计
研究了使用正交空时分组码(OSTBC)与单个接收机通信的多个发射机信道状态信息(CSI)的估计问题。基于秩显示QR (RRQR)分解和传播器方法(PM),提出了两种新的多用户MIMO信道估计算法。该算法估计用户通道所生成的子空间,使用少量的训练块从该子空间中提取用户CSI。与基于LS的参考方法相比,我们的两种算法都取得了更好的性能。计算机模拟包括验证所提出的方法。
