This repository is accompanying the paper "Multi-User Frequency Assignment for Ultra-Reliable mmWave Two-Ray Channels" (K.-L. Besser, E. Jorswieck, J. Coon, WiOpt 2022, Sep. 2022. doi:10.23919/WiOpt56218.2022.9930571, arXiv:2211.07204).

The following files are provided in this repository:

• run.sh: Bash script that runs all of the simulations to reproduce the results from the paper.
• frequency_assignment.py: Python script that implements the simulation of the frequency assignment together with the comparison algorithms.
• util.py: Python module that contains utility functions, e.g., converting to decibel.
• model.py: Python module that contains model-based calculations.
• qmkphp.py: Python module that contains all relevant functions to model and solve the quadratic multiple knapsack problem with heterogeneous profits (QMKP-HP).
• single_frequency.py: Python module that contains the calculations for the single frequency scenario.
• two_frequencies.py: Python module that contains the calculations for the two frequencies scenario.

You can use services like CodeOcean to run the scripts online.

If you want to run it locally on your machine, Python3 and Jupyter are needed. The present code was developed and tested with the following versions:

• Python 3.10
• numpy 1.22
• scipy 1.8

Make sure you have Python3 installed on your computer. You can then install the required packages (including Jupyter) by running

pip3 install -r requirements.txt

This will install all the needed packages which are listed in the requirements file.

You can then recreate all of the simulations by running

bash run.sh
