omodulation and demodulation

otiming and frequency synchronization

ochannel estimation and tracking

oequalization

oFEC integration

oMIMO / beamforming support

oimpairment mitigation and calibration support

· Translate system and link requirements intoimplementation-ready PHY block specifications.

· Develop floating-point, fixed-point, and bit-accurate models for modem PHY functions.

· Perform performance analysis and trade studies across throughput, latency, area, and power.

· Work with architecture and RTL teams to partition algorithms into efficient hardware implementations.

· Support interface definition and subsystem integration for PHY IP within the broader modem/baseband architecture.

· Collaborate with verification teams to define test strategies, reference models, and coverage plans.

· Analyze simulation, emulation, FPGA, lab, and silicon data to debug design issues and improve PHY performance.

· Support bring-up and validation of modem PHY features in FPGA prototypes and silicon.

· Document design assumptions, architecture decisions, performance results, and implementation details.

· Work effectively with internal teams and external design partners to help drive execution.

Minimum Qualifications
