Recent research:
Across the publications, the work integrates advanced wireless communications with optical networking to advance next-generation networks (6G) and beyond. The research compares modulation and signaling strategies (constant envelope vs peak insertion for PAPR reduction in OFDM-IM), evaluates high-speed PAM4-based PONs against legacy PAM2-NRZ, and analyzes GFDM transmission in passive optical networks for high-speed fronthaul in 5G contexts. A common thread is the exploration of performance trade-offs between spectral efficiency, power efficiency, and receiver sensitivity, using simulations and experimental measurements to inform practical deployment. The studies quantify PAPR reductions, BER performance under varying received power and link lengths, and the impact of coherent vs non-coherent detection on fronthaul capacity, while also examining convergence in multi-technology optical access networks. Overall, the work aims to shape green, high-capacity, and cost-aware architectures for future wireless and optical infrastructures, highlighting techniques to optimize power budgets, link budgets, and compatibility between LTE/OFDM-IM, PAM4-PON, GFDM-PON, and optical fronthaul for 5G/6G ecosystems. It also points to dispersion management and compensation strategies as avenues for further optimization.
