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.

本数据集对应论文《基于迁移学习的智能手机众包测量移动下行链路信号电场强度的跨手机校准》。本数据集主要包含通过智能手机与搭载全向天线的频谱分析仪采集到的参考信号接收功率（RSRP）与电场强度数据。本数据集文件包含两个子目录：其一为剔除异常值后的原始数据，其二为预处理特征数据集。详细说明请参阅文件夹内的Readme文件。
1. d1、d2、d3、d4与d5代表采集数据的日期。
2. 2ab、ca1与ef5为手机设备代码。
3. 1850与100为演进型绝对无线频道编号（Earfcn）。
