Low cost and low power is one of the important reasons in the wide application of backscatter sensor networks. Based on LabVIEW and USRP platforms, this paper presents and implements a simple and configurable SDR prototype for backscatter sensor networks. The SDR prototype can apply to the multi-sensor environment with low power. The prototype consists of configurable backscatter transceiver with homodyne receiver and sensor nodes. It can reduce the power consumption of system efficiently through harvesting wireless RF energy and waking sensor nodes. The frequency division multiple access method with configurable sub-carrier is proposed, and the constraint conditions of sensing data pulse period for avoiding collision among sensors are presented and proved in this paper. The performance of the prototype is analyzed, and the closed-form solution of the probability of outage under the log-normal channel is also given and proved. Finally, the experiment and simulation show the SDR prototype is effective and feasible. The EVM value is less than 2.8%, and the probability of outage error between numerical analysis and Monte Carlo simulation is less than 1.86%.
