The Channel Fading Characteristic Measurement Dataset of the North Campus of Xidian University

The measurements in this study were carried out at Xidian University's north campus in China. The building density and height in this area are typical of urban environments, and there are fewer uncertainties that could affect the experimental results. Figure shows an aerial view of the measurement environment, including the chosen Tx and Rx locations. Centered at each receiver, a square with a side length 15 times the wavelength of the transmitted signal was constructed. The receiving antenna was moved inside each square following the path shown in the figure. The transmitter was composed of an SMB100A signal generator manufactured by Rohde \& Schwarz and a 30 dB gain amplifier, set to emit a continuous wave signal at 2.3 GHz with an output power of +43 dBm. During the measurements, the TX antenna was placed on a 2.0 m stand, oriented vertically, and kept stationary at all times. For the receiver, the Rx antenna was mounted on a carbon fiber rod at 2.0 m above ground, secured to a cart to maintain vertical polarization during movement. This antenna was then connected to a Rohde \& Schwarz FSW50 signal and spectrum analyzer using a low-loss coaxial cable. The spectrum analyzer recorded the received signal power incident on the RF input port with a bandwidth of 10 kHz, centered at 2.3 GHz. The received signal power was automatically collected and stored on a laptop through local area network (LAN), with 100 sets of traces stored per second. Both the TX and RX used the same omnidirectional sleeve discone antennas with +4 dBi gain (A-INFO model PZ-100800/P).

本研究的测量实验均在中国西安电子科技大学北校区开展。该区域的建筑密度与高度均契合典型城市环境特征，且存在较少可能干扰实验结果的不确定性因素。附图为测量环境的航拍视图，涵盖选定的发射机（Transmitter, Tx）与接收机（Receiver, Rx）布设位置。以每个接收机为中心，构建了边长为发射信号波长15倍的正方形区域；接收天线沿图中所示路径在该正方形区域内移动。
发射系统由罗德与施瓦茨（Rohde & Schwarz）生产的SMB100A型信号发生器与一台增益30 dB的功率放大器组成，配置为发射频率2.3 GHz的连续波信号，输出功率为+43 dBm。测量期间，发射天线被架设至2.0 m高的支架上，保持垂直定向且全程静止。
接收端的Rx天线安装于距地面2.0 m高的碳纤维杆上，固定于移动小车上以确保移动过程中始终维持垂直极化状态。该天线通过低损耗同轴电缆连接至罗德与施瓦茨FSW50型信号与频谱分析仪。频谱分析仪以10 kHz的带宽、中心频率2.3 GHz记录入射至射频输入端口的接收信号功率。接收信号功率通过局域网（Local Area Network, LAN）自动采集并存储至笔记本电脑，每秒存储100组迹线数据。发射端与接收端均采用型号为A-INFO PZ-100800/P的全向套筒盘锥天线，增益为+4 dBi。
