Fast and Reliable Burst Data Transmission for Backscatter Communications
2019
Sensors
Preserved Fulltext
Computational radio frequency identification (CRFID) sensors are able to transfer potentially large amounts of data to the reader in the radio frequency range. ...
In this paper, we propose a fast and reliable method for burst data transmission by fragmenting large data packets into blocks and we introduce a burst transmission mechanism to optimize the EPC C1G2 communication ...
Then, we fragment large data packets into blocks and design an online adjustment strategy to adjust the frame length and coding redundancy dynamically by the feedback of the reader at runtime. ...

Commercial off-the-shelf Software Defined Radio (SDR) devices are used to demonstrate the practical RF source localisation systems. ...
Compared to the conventional localisation systems, which rely on dedicated hardware, the SDR-based system is developed using general-purpose hardware and software-defined components, offering great flexibility ...
The development software of the USRPs is GNU Radio which is an open source framework for the development of software defined radios, and the "gnuradio-discussion" forum is a useful resource for problem ...
