Abstract
The dataset contains thousands of signal frames from 60 ZigBee devices. The devices and USRP N210 were placed on two movable cabinets on wheels with a maximum distance of 3 meters between them. Due to distance constraints, a coaxial attenuator with an attenuation of 60 dB was fitted at the receiver in order to obtain signals at low SNR. The SNR of the received signal is changed by adjusting the distance between the two cabinets, which can be reduced to about 0 dB when the distance is about 3 metres. The number of samples per device varies from a minimum of over 2,000 frames to a maximum of over 6,000 frames. The SNR of sampled signals is roughly distributed around 0 dB to 30 dB.
Instructions:
All files are in “.mat” format processed on MATLAB. Each file contains two variables, namely " all_data " and "data_index". The raw files obtained from the USRP N210 are not provided, and the files are provided here after performing a simple frame synchronization. Therefore, “all_data” is the complex result of concatenating all frames together, and “data_index” is used to indicate the starting and ending subscripts of each frame.
