Beamforming design for multi-antenna multi-tag symbiotic radio
In this paper, we consider a multi-tag symbiotic radio backscatter system, where a multi-antenna source node transmits its own message to a multi-antenna destination, while
Dual-band cooperative backscatter communication system | IEEE
In this paper, we build a cooperative backscatter communication system in 2.4GHz and 3.5 GHz. A test platform including backscattering modulator, Microcontroller Unit (MCU) and receiver
Backscatter Communications
Extending backscatter communication ranges can be realized using high gain retrodirective arrays and BFNs-based RFID architectures as presented in the previous section.
Backscatter Communications: Inception of the Battery-Free
To understand encoding and data extraction, we demonstrate signal processing aspects that cover channel coding, interference, decoding, and signal detection schemes. Moreover, we
A survey on ambient backscatter communications: Principles,
We first present the basic principles of ambient backscatter communications covering architecture, basic techniques, and primer knowledge of ambient signals. After that,
Dual-Polarization Ambient Backscatter Communications and
We present two different structures for backscatter nodes along with their corresponding transmission models for a DPAm system. Then, we explore a parallel backscatter mode that
A distributed system perspective on Backscatter systems
Backscatter communication, by its nature, often involves distributed elements, especially in bistatic configurations where the radio frequency (RF) source and the receiver are separate
Advances in Wirelessly Powered Backscatter
This article will introduce the state-of-the-art antenna design and radio frequency (RF) system integration for wire-lessly powered backscatter communications, covering both the node and
Advances in Wirelessly Powered Backscatter
We first present the basic principles of ambient backscatter communications covering architecture, basic techniques, and primer knowledge of ambient signals. After that,
Integrated Sensing and Backscatter Communication
This system comprises a full-duplex base station (BS), a backscatter tag, and a user. The tag reflects the BS transmitted signal and provides data to the user. The BS extracts
Multi-Antenna Broadband Backscatter Communications
To overcome these challenges, we introduce a bistatic broadband backscatter communication (BBBC) system, which equips the backscatter device (BD) with multiple antennas.
