• I worked on the development and analysis of satellite communication systems with an emphasis on end-to-end digital link design. The project involved modeling the complete communication chain, from baseband signal generation to reliable data recovery at the receiver.
• I implemented transmitter and receiver modules using MATLAB and Simulink, incorporating standard digital modulation techniques and forward error correction to improve link reliability. To make the system realistic, I modeled practical RF impairments such as noise, frequency and timing offsets, and phase variations, and evaluated their impact on system performance.
• A key part of the work was designing and validating synchronization and signal recovery algorithms that enable stable communication under low signal-to-noise conditions. System performance was analyzed using metrics like bit error rate, packet error rate, constellation diagrams, and spectrum analysis.
• In addition, I carried out link-level performance evaluation to study power requirements and overall system robustness under practical operating conditions. This project helped me gain strong hands-on experience in translating communication theory into deployable, standards-oriented system models, while maintaining a clear separation from any proprietary or confidential information.

• Modem Design :
• Designed a complete communication system modem for S-Band in MATLAB/Simulink, processing 114,493 audio samples through companding, quantization, source coding, line coding, and 4-QAM modulation; implemented inverse operations at the receiver and converted the model to HDL for FPGA-based real-time processing in satellite, radar, and wireless applications.
• Performed link budget analysis using MATLAB's Satellite Link Budget Analyzer App and Ansys STK Software to evaluate signal strength, power requirements, and overall communication system performance under realistic satellite conditions.
