Frequency Shift Keying Scheme to Implement SDR using Hackrf one

摘要

Software-defined radio concept offers high flexibility through the modulation/demodulation functionality implemented in software. HackRF one is an open mid-range SDR hardware platform which is available in the market. Proposed method was designed and experimentally carried out to transmit and receive digital data source through GFSK scheme. Four scenarios were designed which were scenario I, II, III and IV by placing the transmitter and receiver in frour different positions and conditions. The digital data source was in form of wav music. The results show that the digital data was successfully transmitted in all scenarios. Each scenario produced different signal power where it was 12dB, 10dB, 9 dB and 5dB for scenario I, II, III and IV respectively. It can be concluded that HackRF one as a mid-range hardware platform has been successed to perform SDR transmission.
