Intern- Signal Processing

Coherent

4d • Onsite

About The Position

We are seeking a highly motivated Signal Processing Intern to join our T&D, Manufacturing Services team. The successful candidate will contribute to our ongoing projects focused on Transmitter and Dispersion Eye Closure Quaternary (TDECQ) measurement, analysis, and validation. You will have the opportunity to work on sophisticated signal processing tasks, refine measurement techniques, and ensure our products meet and exceed industry standards.

Requirements

• Currently enrolled in or recently graduated from a degree in Electrical Engineering, Computer Science, or a related field with a focus on signal processing or telecommunications.
• Solid understanding of digital signal processing concepts and adaptive filter algorithms, preferably with knowledge of LMS and FFE.
• Familiarity with PAM4 modulation schemes and optical communication principles.
• Experience with MATLAB, Python, C# or similar programming languages and tools used for signal analysis.
• Excellent problem-solving skills and the ability to work independently as well as collaboratively in a team.
• Strong communication skills with the ability to present complex technical information clearly and concisely.

Responsibilities

• Develop and optimize signal processing algorithms for accurate TDECQ measurement in PAM4 waveforms.
• Implement noise simulation techniques and intrinsic noise parameters to enhance signal fidelity.
• Engage in de-embedding S-parameters for precise characterization of photodiodes and amplifiers within test setups.
• Collaborate with the team to validate TDECQ calculations for electrical inputs on Digital Communication Analyzers (DCA).
• Assist in refining methods for histogram optimization and threshold optimization for signal analysis.
• Conduct comparative analysis across multiple channels and DCA types to standardize TDECQ and EECQ algorithms.
• Participate in drafting technical documentation and reports for internal and external stakeholders, including standardization bodies such as IEEE.
