Real-time communication system design using RTL-SDR and Raspberry Pi
R. Danymol, T. Ajitha, R Gandhiraj · 2013
RTL-2832U USB receiver - Raspberry Pi setup receives and decodes the FM signals and sends to another computer across the Local Area Network. It can be realized by means of SDR-Sharp software in remote PC; hence it can be used for communication. Raspberry Pi is a low cost, credit-card sized computer. Whereas RTL-2832U USB receiver has a mode where it dumps raw IQ samples over USB to the computer. The GNU Radio experiments supports this relatively cheap USB receiver as a software defined radio. Using GNU Radio Companion, all real-time communication experiments can be reproduced.
