摘要:

物联网(IoT)和机器对机器(M2M)通信等新兴系统对所用设备的功耗以及收发器设计的相关复杂性有严格的要求。结果,由于多输入多输出(MIMO)解决方案的高复杂度、天线间同步(IAS)要求和高天线间干扰(IAI)问题,它们可能不直接适用于这些系统。为了克服这些问题,我们提出了两个新的索引调制(IM)方案,即脉冲索引调制(PIM)和广义PIM(GPIM)的单输入单输出(SISO)计划。所提出的模型使用良好的本地化和正交厄米高斯脉冲的数据传输,并提供高的频谱效率,由于厄米高斯脉冲指数。此外,它已通过分析推导和计算机仿真表明,建议PIM和GPIM系统具有更好的错误性能和相当大的信噪比(SNR)增益相比,现有的空间调制(SM),正交SM(QSM),和传统的M进制系统。

英文摘要:

Emerging systems such as Internet-of-things (IoT) and machine-to-machine (M2M) communications have strict requirements on the power consumption of used equipments and associated complexity in the transceiver design. As a result, multiple-input multiple-output (MIMO) solutions might not be directly suitable for these system due to their high complexity, inter-antenna synchronization (IAS) requirement, and high inter-antenna interference (IAI) problems. In order to overcome these problems, we propose two novel index modulation (IM) schemes, namely pulse index modulation (PIM) and generalized PIM (GPIM) for single-input single-output (SISO) schemes. The proposed models use well-localized and orthogonal Hermite-Gaussian pulses for data transmission and provide high spectral efficiency owing to the Hermite-Gaussian pulse indices. Besides, it has been shown via analytical derivations and computer simulations that the proposed PIM and GPIM systems have better error performance and considerable signal-to-noise ratio (SNR) gain compared to existing spatial modulation (SM), quadrature SM (QSM), and traditional M-ary systems.
