分子MIMO的空间编码技术
Spatial Coding Techniques for Molecular MIMO
摘要:
本文研究了空间分集技术在多输入多输出(MIMO)扩散分子通信(DBMC)中的应用。提出并分析了两种空间编码技术,即Alamouti型编码和重复MIMO编码。此外,我们考虑接收端等增益合并,这是相当于对称情况下的最大比合并。为了进行数值分析,利用训练好的人工神经网络获得了对称$2 \times 2$ MIMO-DBMC系统的信道冲激响应。结果表明,空间分集有可能提高系统性能,重复MIMO编码优于Alamouti型编码。
英文摘要:
This paper studies spatial diversity techniques applied to multiple-input multiple-output (MIMO) diffusion-based molecular communications (DBMC). Two types of spatial coding techniques, namely Alamouti-type coding and repetition MIMO coding are suggested and analyzed. In addition, we consider receiver-side equal-gain combining, which is equivalent to maximum-ratio combining in symmetrical scenarios. For numerical analysis, the channel impulse responses of a symmetrical $2 \times 2$ MIMO-DBMC system are acquired by a trained artificial neural network. It is demonstrated that spatial diversity has the potential to improve the system performance and that repetition MIMO coding outperforms Alamouti-type coding.
