cross-phone calibration dataset

This is the dataset used in the paper "Cross-phone calibration for smartphone-based crowdsourced measurement of E-field strength of mobile downlink signals using transfer learning". The dataset is mainly composed of RSRP and E-field strength data collected using smart phones and the Spectrum Analyzer with isotropic antenna. The file contains two subdirectories, one for the raw data after removing the outliers and the other for the preprocessed feature dataset. See the Readme file in the folder for details. 1. d1, d2, d3, d4, and d5 denote day of the collected data.2. 2ab, ca1, and ef5 are the code of the phone3. 1850 and 100 are the Earfcn.
