Wireless Systems R&D Consultant | MIMO, NOMA & UAV Networks | Advanced MATLAB & Python Simulation

Profile Summary

I am an academic professor and Wireless Communications Researcher specializing in the physical (PHY) and medium access control (MAC) layers of advanced wireless networks. I bridge the gap between complex mathematical theory and working system-level simulations. With a deep background in academic research, I offer freelance R&D consulting services focused on algorithm design, performance analysis, and radio resource optimization for next-generation networks (5G/6G). Unlike generalist developers, I understand the underlying stochastic geometry and signal processing mathematics required to build accurate, high-fidelity wireless simulations. Core Technical Expertise: System-Level Simulation: Building custom simulation environments from scratch in MATLAB and Python to validate theoretical models. Advanced Technologies: Expertise in MIMO (Massive, MU-MIMO), NOMA (Non-Orthogonal Multiple Access), and UAV-assisted (Unmanned Aerial Vehicle) communication networks. Optimization: Convex and non-convex optimization for radio resource allocation (power control, trajectory optimization, user scheduling). Signal Processing: Design and analysis of baseband algorithms, channel estimation, and interference management. Services I Offer: Algorithm Validation: Reviewing mathematical derivations in technical papers and validating them through Monte Carlo simulations. Code Optimization: Refactoring slow or inefficient research code into vectorized, high-performance scripts. Technical Review: Critical analysis of patents, white papers, and technical manuscripts for accuracy and novelty.
