o modulation and demodulation

o timing and frequency synchronization

o channel estimation and tracking

o equalization

o FEC integration

o MIMO / beamforming support

o impairment 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.
