论文摘要
本文通过选择组合（SC）多样性接收到多载体索引键盘多路复用（MCIK -OFDM）的多载体指数键控（MCIK -OFDM）的位错误率（BER）。特别是，我们提出了一个广义框架，以得出低复杂性贪婪检测器（GD）和最大似然（ML）检测器的BER。基于此，使用ML或GD使用SC的MCIK-OFDM BERS的封闭形式表达式在存在通道状态信息（CSI）缺陷的情况下得出。提出了渐近分析，以获取对不同CSI条件对这两个检测器的BER的影响的有益见解。更重要的是，从理论上讲，我们提供了使用GD而不是在每个特定CSI不确定性下使用ML的机会，这取决于接收器天线的数量和M-ARY调制大小。最后，提供了广泛的仿真结果，以验证我们的理论表达和分析。
This paper analyzes the bit error rate (BER) of multicarrier index keying - orthogonal frequency division multiplexing (MCIK-OFDM) with selection combining (SC) diversity reception. Particularly, we propose a generalized framework to derive the BER for both the low-complexity greedy detector (GD) and maximum likelihood (ML) detector. Based on this, closedform expressions for the BERs of MCIK-OFDM with the SC using either the ML or the GD are derived in presence of the channel state information (CSI) imperfection. The asymptotic analysis is presented to gain helpful insights into effects of different CSI conditions on the BERs of these two detectors. More importantly, we theoretically provide opportunities for using the GD instead of the ML under each specific CSI uncertainty, which depend on the number of receiver antennas and the M-ary modulation size. Finally, extensive simulation results are provided in order to validate our theoretical expressions and analysis.
