用于高速可见光通信的多层相移线性空时分组码
Multiple layer Phase Shift Linear Space-time Block Code for High-speed Visible Light Communications
摘要：
在这封信中，我们考虑强度调制/直接检测（IM/DD）信道中的可见光通信（VLC）系统与多个发射机磷光体基白光发光二极管（LED）和单接收雪崩光电二极管（APD）。提出了一种多层相移线性空时分组码（MLPS-LSTBC）。我们证明了我们提出的VLC码具有以下主要特征：（a）符号传输速率为$N/(N+M-1)$，其中$N$是发射机LED的数目，$M$表示每层单个码字所包含的移位间隔的数目;（b）迫零接收机即使在接收机侧没有信道状态信息（CSIR）的情况下也可以将虚拟MIMO矩阵信道变换为并行子信道;（c）我们的MLPS-LSTBC可以通过$\min (M\text{,}N)$渐进地提高频谱效率，这对于具有有限电调制带宽的基于LED的VLC是有吸引力的。通过仿真，我们实现了1.5 Gb/s的记录数据率，通过多次100 M波特的OOK信号传输，出错率性能低于$2\times10^{-3}$的FEC限制。
英文摘要：
In this letter, we consider intensity modulation/direct detection (IM/DD) channel in the visible light communication (VLC) systems with multiple transmitter phosphor-based white light emitting diodes (LED) and single receiver avalanche photo diode (APD). We proposed a Multiple Layer Phase Shift Linear Space-time Block Code (MLPS-LSTBC). We show that our proposed code for VLC has the following main features: (a) The symbol transmission rate is $N/(N+M-1)$, where $N$ is the number of transmitter LED and $M$ denotes the number of shift intervals contained by a single codeword per layer; (b) zero-forcing receiver can transform the virtual MIMO matrix channel into parallel sub-channels even without channel state information at the receiver side (CSIR); (c) Our MLPS-LSTBC can asymptotically enhance the spectral efficiency by $\min (M\text{,}N)$, which is attractive for LED-based VLC with limited electrical modulation bandwidth. By simulations, we achieve the record data rate of 1.5 Gb/s with the bit error rate performance below the FEC limit of $2\times10^{-3}$ via multiple 100-MBaud transmission of OOK signal.
