Initial Release - Optimal Partitioning Algorithms for RIS/IRS Beamforming

This is the first public release of the Optimal Partitioning Algorithms (OPA) software for discrete beamforming with Intelligent Reflecting Surfaces (IRS/RIS).

Implemented Algorithms

  • OPA_1bit_1beam: Single beam, 1-bit quantization (Algorithm 3 - gOPA)
  • OPA_1bitpre_1beam: Single beam, 1-bit with prephasing (Algorithm 3 - gOPA)
  • OPA_1bitpre_2beam: Dual beam, 1-bit with prephasing (Algorithm 5)
  • OPA_kbit_1beam: Single beam, k-bit quantization (Algorithm 4 - kOPA)
  • OPA_kbit_2beam: Dual beam, arbitrary k discrete weights (Algorithm 5)
  • kary_algorithm: Helper function for k-ary partitioning

Features

  • ✓ Support for 1-bit (binary) and k-bit (multi-level) phase quantization
  • ✓ Single and dual beam forming capabilities
  • ✓ Optional prephasing support for element-specific constraint sets
  • ✓ Efficient algorithms with polynomial complexity
  • ✓ Radiation pattern visualization
  • ✓ Comprehensive documentation with sample invocations

Documentation

  • Complete README with detailed function signatures and parameter descriptions
  • Sample invocations for all functions
  • Sign convention clarification with diagrams
  • CITATION.cff file for easy citation
  • How to cite section with BibTeX
