Open-Source Pathloss Map (Large-Scale Channel) Prediction Dataset

These channel data were created, and are made available, by the WiDeS group at USC; specifically they are based on ray-tracing simulations conducted by Dr. Zheda using the ray-tracing tool Wireless Insite and a database of the geographical and morphological features of the propagation environment, i.e., the University Park Campus of USC. The dataset was then prepared through pre-processing methods such as interpolation and data augmentation by Dr. Juhyung Lee. The details of the dataset can be found in [Lee 2022a]. If you have any questions regarding the data, please email Juhyung Lee at juhyung.lee@usc.edu.

Code for generating files with realistic popularity distribution

This code is used to generate individual preferences of users. We provide two functions that can generate individual preferences of users based on two real-world dataset. The details of the modeling and parameterization, and the recipe of the generator can be found in [Lee, 2019]. The use of the generator should be as simple as using a Matlab function. Please find the functions and see the Readme file in the download.

Open-Source Cell-Free Massive MIMO Channel Data 2020

These channel data are obtained from channel measurement campaigns between the drone transmitter and a 128-element cylindrical antenna array receiver. The drone flew across a trajectory on the University Park campus of USC acting as an access point and the receiver was put into four different locations. The measurement was conducted at 3.5 GHz, with 46 MHz bandwidth and 2301 subcarriers. The details of the measurement campaign can be found from [Choi2021Using]. If you have any questions regarding the data, please email Thomas Choi at choit@usc.edu.
