IRFi-SDR: An IR software defined radio

2019 Global LIFI Congress (GLC), 2019
We present our case-study of a software defined radio transreciever for the communication in the near infrared spectrum for indoor communication. It's based on a FPGA development board with a custom transceiver. As an infrared fidelity software defined radio (IRFi-SDR) is build, several modulation schemes can be implemented.

Applications of software-defined radio (SDR) technology in hospital environments

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
A software-defined radio (SDR) is a radio communication system where the major part of its functionality is implemented by means of software in a personal computer or embedded system. Such a design paradigm has the major advantage of producing devices that can receive and transmit widely different radio protocols based solely on the software used. This

Retrodirective Cross-Eye Jammer Implementation using Software-Defined Radio (SDR)

2021 IEEE Radar Conference (RadarConf21), 2021
Extremely few implementations of retrodirective cross-eye jamming have been published, and those that have either only present results without providing implementation details or are not true retrodirective cross-eye jammers. To address this limitation, the implementation and testing of a retrodirective cross-eye jammer against a phase-comparison ...
