“…The fifth generation of mobile communications (5G) will meet the growing demand for high-speed data transmission, large capacity and ubiquitous connectivity, as the global positioning system (GPS) [ 1 , 2 ], satellite digital audio radio service (SDARS) [ 3 , 4 ], cellular communication [ 5 , 6 , 7 ] and vehicle-to-everything (V2X) communication [ 8 , 9 ] meet the needs of navigation, communication and entertainment. As the amount of information sources increases, V2X communication will become more crowded and there will be a faster fading issue, which leads to a decline in efficiency.…”

This paper presents an MIMO antenna for vehicle-to-everything (V2X) communication, which adopts two ways of combline filters and absorption wall decoupling. A combline filter and an absorption wall are used, respectively, for internal and external decoupling. The combline filter is incorporated between the ground of the two adjacent antennas, which reduces the mutual coupling between them. Additionally, the mutual coupling of radiation between adjacent antennas is significantly reduced by the absorber wall. These combline filters and absorber walls use the method of electromagnetic field distribution to explain the reduction in the mutual coupling between the adjacent antennas. The transmission coefficient and surface current distribution explain the effectiveness of the decoupling structure. When the frequency is between 3.8 and 4.8 GHz, the simulation and measurement results show that S11 is less than −10 dB, the bandwidth is 25% and the peak gain is 7.8 dBi. In addition, the proposed MIMO antenna has a high isolation between antenna units (>37 dB), and the envelop correlation coefficient (ECC) is less than 0.005.

“…While this approach offers a unique solution for real-time hardware functional updates, it necessitates a high network reliability level and is unsuitable for the varied scenarios in IoT applications. Some researchers have tackled this issue by proposing functional updates based on In-application Programming (IAP) [23]- [25]. This approach involves the separation of boot code and application code, thereby offering a potential solution to the challenge of ensuring dependable hardware functional updates in Microcontroller Unit (MCU) platforms.…”

The rapid growth of the Internet of Things (IoT) market has made serial buses a universal transmission method for connecting various devices and carrying large amounts of heterogeneous data. Existing methods of processing heterogeneous serial bus data rely on programmable devices such as FPGAs and MCUs to solve the data heterogeneity problem by updating the system firmware functions. However, these methods are constrained by professional developmemt knowledge, hardware platform compatibility, system reliability, and security, leading to the inflexibility and inefficiency of programmable devices to process serial bus heterogeneous data. In this paper, we propose a novel Software-defined Interaction (SDI) approach that enables dynamic configuration of heterogeneous bus data and can process different data types by introducing a scripting language into a low-cost embedded device. Specifically, a Lightweight Data Distribution (L2D) mechanism is presented to address the strong dependency between data and protocols, which achieves efficient decoupling between data and processing methods. Additionally, a Multi-instance Hot-switching (MIHS) method is proposed to achieve dynamic switching among multiple instances. Finally, the effectiveness and real-time performance of the proposed method are verified through simulation and lowcost hardware deployment.INDEX TERMS heterogeneous data, low-cost embedded device, software-defined interaction, data distribution, hot-switching.
