Currently, most of the technical solutions for wireless communications and navigation systems prototyping and validation in academic and scientific community employ Software Defined Radio (SDR) technology. However, wider utilizing of popular and well proven SDR platforms, such as USRP (Universal Software Radio Peripheral), LimeSDR and AD-FMCOMMS boards, is still difficult due to high cost and low availability. One of the solutions to popularize and make SDR wireless communication technology design more accessible for academic and scientific community is the emerging low-cost SDR-platform LibreSDR. Current work is devoted to experimental validation of LTE compliant transmission and reception of reference signals on physical layer, using LibreSDR board. The results of the experimental validation prove the potential of relatively low-cost LibreSDR utilization for wireless communications and navigation systems prototyping with the same performance, as well known USRP boards, among young scientists and students during their education and research in the academic and scientific community.
