Side-information-Aided Non-coherent Beam Alignment (SANBA) for MmWave Systems.

The SINBA algorithm is designed and prototyped with MATLAB, USRP and phased arrays.

This repository contains the source codes for the following paper:

Yi Zhang, Kartik Patel, Sanjay Shakkottai, and Robert W. Heath Jr.. 2019. Side-information-aided Non-coherent Beam Alignment Design for Millimeter Wave Systems. In MobiHoc '19: The Twentieth ACM International Symposium on Mobile Ad Hoc Networking and Computing, July 02-05, 2019, Catania, Italy. ACM, New York, NY, USA, 10 pages. [Link]

In particular, this repository contains the experimental validation and numerical simulation of the contribution of the above paper. Details of the method, experimental results, and representative numerical results can be also found in the above paper.

This software was developed at the Department of Electrical and Computer Engineering, The University of Texas at Austin and is released under the MIT license.

The software was developed and tested using Matlab R2017b, and uses SparsePR, a Matlab software package for solving the sparse phase retrieval problem, and TFOCS, a Matlab software package for the efficient construction and solution of convex optimization problems. A copy of the sparsepr package is included under the third party software directory at "Numerical_Simulation/3rd_software_component/". A selection of scripts also uses the CVX optimization software, the Generalized Approximate Message Passing (GAMP) in MRI MATLAB package and the CoSaMP/OMP toolbox.

Directory Structure and Contents

The software package is organized under the following directory structure:

• Experimental_Validation/

  • data/

    • cal_data/ - This folder contains the collected data which will be used to calibrate the antennas, i.e. calculating the radiation gain and phase error of each antenna element of a phased array.
    • cal_result/ - This folder contains the calibration result after running the functions in [Experimental_Validation/main_programs/ fine_phased_array_calibration/].
    • val_cal_data/ - This folder contains the collected data which will be used to validate the proposed calibration method by testing the RSSI of the directional beam patterns.
    • val_cpr_data/ - This folder contains the collected data which will be used to validate the proposed two-stage non-coherent beam alignment algorithm.

  • main_programs/

    • cal_decoder/ - This folder contains the specific decoder to decode the collected calibration data to check more details of the performance of the proposed calibration methods.
    • fine_phased_array_calibration/ - This folder contains the main scripts for calculating the radiation gain and the phase error of the phase shifters of a phased array.
    • general_receiver_decoder/ - This folder contains the general receiver and decoder to run the testbed.
    • general_transmitter/ - This folder contains the general transmitter to run the testbed.
