Abstract
Ambient Backscatter Communication System (ABCS) is regarded as one of the core technologies in the Internet of Things (IoT) due to its ultra-low power consumption and low-cost advantages. However, it also faces multiple challenges in terms of communication reliability, coverage range, and Spectral Efficiency (SE), which constrain its application potential in dense networks and complex scenarios. In this paper, we apply Simultaneous Transmitting and Reflecting Reconfigurable Intelligent Surface (STAR-RIS) with pattern technology and Index Modulation (IM) into ABCS to improve the SE and Bit Error Rate (BER) performance as well as coverage range. Specifically, the proposed scheme enables extra information bits to be transmitted by allocating subsurfaces to different Backscatter Tags (BTs) and leveraging antenna combinations formed by active antennas of BTs. Meanwhile, the integration of STAR-RIS into ABCS not only significantly enhances signal strength but also achieves full communication coverage. Furthermore, the theoretical and simulation analysis of BER for the proposed scheme is investigated, which reveals the reliability of this scheme with high SE and comparable BER performance.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
