In this role, core responsibilities include, but are not limited to, the following:•Design radio models for the wireless communication system, RF/circuits impairments. Design method/algorithm to alleviate those impairments by calibration, pre-equalization, canceller, and/or pre-distortion techniques.•Evaluate radio performance in different scenarios by quantitative analysis and link simulation.•Work with radio designer to come up with state-of-art radio architecture.•Work with digital designers to realize PHY/radio algorithms with power and area efficient digital implementations.•Work with firmware designers to realize PHY/radio algorithms with high efficiency software implementation, and possibly with hardware acceleration.•Responsibility for Bring up, test, characterize and optimize real silicon in lab.
