Smart Sensing Strategy for Wireless Channel Based on Sequence Characterizes Matching Method

In this paper, we use the software-defined radio platform GNU Radio + USRP to implement a GSM channel smart sensing system by using the wireless channel smart sensing strategy based on sequence characterizes matching method. We adopted multi-step to design the system from physical layer. First, we rough scan the signal intensity of GSM channels, then select the channel that has better signal intensity to precise scan and save the data. Then, according to the sequence characterizes of different type channel, we analysis these data and realize the utilization rate of channels.
