This is a python code package related to the following article: H.Luo, U. Demirhan and A. Alkhateeb, "Millimeter Wave V2V Beam Tracking using Radar: Algorithms and Real-World Demonstration", accepted to 2023 31st European Signal Processing Conference (EUSIPCO).

Abstract of the Article

Utilizing radar sensing for assisting communication has attracted increasing interest thanks to its potential in dynamic environments. A particularly interesting problem for this approach appears in the vehicle-to-vehicle (V2V) millimeter wave and terahertz communication scenarios, where the narrow beams change with the movement of both vehicles. To address this problem, in this work, we develop a radar-aided beam-tracking framework, where a single initial beam and a set of radar measurements over a period of time are utilized to predict the future beams after this time duration. Within this framework, we develop two approaches with the combination of various degrees of radar signal processing and machine learning. To evaluate the feasibility of the solutions in a realistic scenario, we test their performance on a real-world V2V dataset. Our results indicated the importance of high angular resolution radar for this task and affirmed the potential of using radar for the V2V beam management problems.

Code Package Content

The scripts for generating the results of the end-to-end ML solution in the paper. For the beam tracking with transmitter identification, please refer to this branch. This script adopts Scenario 36 of DeepSense 6G dataset.

To implement our solution, please follow these steps:

Download Dataset and Code

1. Download Scenario 36 of DeepSense 6G dataset
2. Download (or clone) the repository into a directory
3. Extract the dataset into the repository directory

Generate Development Dataset

1. Move the scripts in preprocess/ to the dataset directory
2. To focus on the scenarios interesting for tracking, we manually filter the data by keeping the sequences of samples with changing beam indices (e.g., the transmitter getting closer to the receiver in a different lane or the vehicles consecutively taking a turn). If you want to use other V2V scenarios (Scenario 37-39), the following scripts can help you check the beam indices and filter the dataset.

python plot_beam_vs_time.py

python generate_selected_dataset.py

3. Preprocess the radar data

python radar_preprocess.py \
  --out_dir unit1_selected_mat/ \
  --log

4. Generate the train/val/test sets
