Akif Kabacı, Mehmet Başaran, Hakan Ali Çırpan

摘要:

在这封信中,我们研究了参考信号辅助信道估计的概念,这是一个至关重要的要求,以解决现实的性能空间基于媒体的调制(SMBM)系统的射频反射镜部署随着多个发射天线。因此,在文献中首次提出了基于最小二乘和线性最小均方误差的信道估计方案,用于基于MBM的系统,以前的研究主要假设或者完美的信道状态信息或者信道系数的误差模型。此外,还研究了相应的符号检测性能。为了衡量所提出的信道估计方法的效率,平均误比特率的理论上界推导和示出的是很好的重叠与计算机模拟的中,高信噪比区域。该研究对于基于多载波调制的通信系统的信道估计的实现以及检测界的理论推导具有重要意义。

英文摘要:

In this letter, we study the reference signal-aided channel estimation concept which is a crucial requirement to address the realistic performance of spatial media-based modulation (SMBM) systems where the radio frequency mirrors are deployed along with the multiple transmit antennas. Accordingly, least squares and linear minimum mean square error-based channel estimation schemes are proposed for MBM-based systems for the first time in the literature where former studies mainly assume either perfect channel state information or an error model on channel coefficients. In addition, corresponding symbol detection performance is studied. To measure the efficiency of the proposed channel estimation approaches, the theoretical upper bounds on average bit error rate are derived and shown to be well overlapped with the computer simulations for the medium and high signal-to-noise ratio regions. This study is important due to the implementation of channel estimation as well as the theoretical derivation of detection bounds for MBM-based communication systems.
