# RF Beamforming Optimizer - Reproducible LaTeX Paper Kit

## Overview

This package provides a complete, reviewer-ready IEEE-style LaTeX paper for RF beamforming optimization using Q-learning. The paper includes auto-generated figures, tables, sweep analysis, and ablation studies with one-command builds.

## Quick Start

```bash
# Complete build with all figures, tables, and sweep analysis
make -f Makefile_beam pdf-full

# Basic build (no sweep analysis)
make -f Makefile_beam pdf

# Individual components
make -f Makefile_beam tables    # Generate metrics and TeX tables
make -f Makefile_beam figs      # Generate plots and figures
make -f Makefile_beam sweep     # Run parameter sweeps and ablation
```

## Core Algorithm

The implementation uses tabular Q-learning (PyTorch-free) for RF beamforming optimization:

- **State Space**: Signal quality, interference, beam history
- **Action Space**: Discrete beam directions (8-16 options)
- **Environment**: Dynamic RF conditions with drift and interference
- **Learning**: ε-greedy exploration with experience replay

## Parameter Sweeps & Ablation

The sweep analysis evaluates:
- **Action Dimensions**: 8, 12, 16 beam directions
- **Target Update**: 10, 20, 40 step intervals  
- **Replay Capacity**: 5K, 10K, 20K experience buffer sizes

Results show optimal configuration and sensitivity to hyperparameters.

## Dependencies

- **Python**: numpy, matplotlib, random, json, time
- **LaTeX**: IEEEtran, booktabs, graphicx, cleveref, listings, url
- **Build**: latexmk, make

No PyTorch or heavy ML dependencies required.

## Reproducibility

All results are deterministic with fixed random seeds. The complete build pipeline:

1. **Training**: Runs Q-learning with logging
2. **Evaluation**: Compares against baselines  
3. **Sweeps**: Parameter sensitivity analysis
4. **Tables**: JSON → TeX conversion
5. **Figures**: Auto-generated plots
6. **PDF**: LaTeX compilation with bibliography

## Output

- **main_beamforming.pdf**: 4-page IEEE conference paper (690KB)
- Complete with references, figures, tables, and appendix
- Reviewer-ready with quantified results and statistical analysis

## Customization

- Modify `scripts/beam_bench.py` for different training configurations
- Edit `scripts/beam_sweep.py` to add new parameter ranges
- Update `main_beamforming.tex` for content changes
- Extend `references.bib` for additional citations

## Validation

The package has been tested end-to-end with successful:
- Q-learning training convergence
- Figure and table generation  
- LaTeX compilation without errors
- Parameter sweep completion
- Reproducible builds

All components integrate seamlessly for submission-ready output.
