| Abstract: | A GNU Radio software platform and USRP based measurement system which can measure real-time wireless signal intensity is proposed in this paper.By analyzing the basic blocks of the measurement system and the realization of the relevant module,we eventually build the measurement system.The system is of high scalability and good portability.The proposed measurement system can both use a single frequency sine wave and a GMSK modulation signal as a transmitting signal to measure the path loss.Test in actual environment and the analysis of the measured data prove the feasibility of the proposed system. |
