This project implements MATLAB simulations of hostile wireless channels, focusing on:
- Rayleigh fading with Doppler shift and delay spread.
- Channel parameter extraction (delay, coherence time, coherence bandwidth).
- DBPSK modulation and demodulation.
- OFDM modulation with multiple subcarriers.
- BER vs. SNR and bitrate analysis.

Practica_HostilsThis runs a Rayleigh channel simulation with DBPSK modulation and produces BER vs. SNR plots.
- Channel simulation: generate PN sequences, apply Rayleigh fading with Doppler/delay.
- Modulation: DBPSK and OFDM schemes implemented in MATLAB scripts.
- Performance analysis: run BER vs. SNR/bitrate sweeps.
- Visualization: scattering function, transfer function, BER curves.
- End-to-end hostile channel simulation
- BER analysis under fading and noise
- OFDM multi-carrier transmission
- Modular MATLAB scripts for reproducibility
- Smoke test: ensure scripts run and generate plots in
/build/. - BER validation: compare theoretical vs. simulated BER for DBPSK.
- OFDM validation: confirm subcarrier parallelism and BER improvement.
- Modeling Rayleigh fading channels in MATLAB
- Extracting channel parameters (Doppler, delay spread)
- Trade-offs between DBPSK and OFDM in hostile conditions
- Structuring MATLAB academic work into a professional repository
- Add smoke test script under
/test/ - Automate plot exports into
/build/ - Add OFDM multi-carrier BER vs. SNR analysis
- Compare with alternative modulation schemes (QPSK, 16-QAM)
