“…Wu et al [39] investigated the beamforming design optimization problem that maximizes the transmission capacity, and provided an exact penalty method that can achieve the capacity closed to the upper bound. Tao et al [40] discussed the interference cancellation problem of Bistatic backscatter communication system and developed a optimal detector to cancel the direct path interference. Felisberto et al established good practices for the design of IoT devices with a focus on two main design challenges i.e., power consumption and the connectivity, and discussed the challenges of resource constrained IoT devices [10].…”

With the popularization of Internet-of-things (IoT) and wireless communication systems, a diverse set of applications in smart cities are emerging to improve the city-life. These applications usually require a large coverage area and minimal operation and maintenance cost. To this end, the recently emerging backscatter communication (BC) is gaining interest in both industry and academia as a new communication paradigm that provides high energy efficient communications that may even work in a battery-less mode and, thus, it is well suited for smart city applications. However, the coverage of BC in urban area deployments is not available, and the feasibility of its utilization for smart city applications is not known. In this article, we present a comprehensive coverage study of a practical cellular carrier-based BC system for indoor and outdoor scenarios in a downtown area of a Helsinki city. In particular, we evaluate the coverage outage performance of different low-power and wide area technologies, i.e., long range (LoRa) backscatter, arrow band-Internet of Things (NB-IoT), and Bluetooth low energy (BLE) based BC at different frequencies of operation. To do so, we carry out a comprehensive campaign of simulations while using a sophisticated three-dimensional (3D) ray tracing (RT) tool, ITU outdoor model, and 3rd generation partnership project (3GPP) indoor hotspot model. This study also covers the energy harvesting aspects of backscatter device, and it highlights the importance of future backscatter devices with high energy harvesting efficiency. The simulation results and discussion provided in this article will be helpful in understanding the coverage aspects of practical backscatter communication system in a smart city environment.

“…Another solution is utilizing the periodicity of carrier signals to suppress interference. In that direction, authors in [149] leveraged the periodic nature of sinusoidal carrier signals to suppress interference in bistatic BackCom by designing an optimal detector at the receiver.…”

“…The authors in [39] worked on independent component analysis (ICA) scheme based on maximum likelihood (ML) principle rather than just conventional ICA scheme to minimize BER. In the multiple antenna ambient backscatter scenarios, the characterization of BER was established in [40] and [41] by the energy detector and the maximum-eigenvalue detector. Employing likelihood ratio test maximum-eigenvalue detector is shown to outperform other energy detectors.…”
