This repository packages a Wireless Communications practice folder into a public, reviewer-ready engineering portfolio. It contains MATLAB simulations, lecture PDFs, and test-preparation material for radio propagation, fading channels, BPSK BER, channel estimation, equalizers, OFDM, MIMO SVD precoding, transmit antenna selection, selection combining, and Alamouti diversity.
The public framing is deliberately restrained: this is academic MATLAB and communications-engineering evidence, not a deployed radio product. The value is in the modeling assumptions, Monte Carlo verification, plotted performance comparisons, and clean English documentation for HR, faculty, seminar, and IEEE-style engineering review.

- Open MATLAB.
- Set the repository root as the current folder.
- Add the relevant lab folder to the MATLAB path when a script calls helper functions from the same lab.
- Open one
.mfile frommatlab/Lab 01throughmatlab/Lab 06. - Run the script and inspect the generated BER, outage probability, PDF, or capacity plot.
- Compare plotted simulation markers against the theoretical curves or check arrays embedded in the script.

- Public Markdown text, tables, image captions, plot labels, and release notes are written in English (United States).
- MATLAB comments and plot legends were cleaned to remove mojibake and non-English visible labels.
- SVG text is ASCII-safe English only.
- Visual assets avoid moving dotted paths, curved connector lines, and any text placed behind line graphics.
- Claims are limited to repository-backed academic evidence.

| Question | Answer |
|---|---|
| Is this a production wireless system? | No. It is an academic MATLAB simulation portfolio for communications-engineering review. |
| What should HR or faculty reviewers inspect first? | Start with the evidence map, then open the recommended MATLAB scripts and release notes. |
| Why are lecture and exam PDFs included? | They document the course scope and connect the scripts to test and seminar preparation. |
| Are the equations and simulations complete? | The repository preserves the coursework scripts and adds English review structure; detailed derivations remain in the lecture PDFs. |
| What is the strongest technical signal? | BER and capacity comparisons across fading, equalization, OFDM, SVD precoding, and diversity methods. |
This repository is presented as course and portfolio evidence for Electronics and Telecommunications Engineering. It should be reviewed as MATLAB simulation, academic preparation, and communications-system reasoning. It does not claim hardware radio deployment, production validation, or original ownership of all lecture or exam materials.
