Description

In this role, core responsibilities include, but are not limited to the following: Designing and simulating wireless communication systems for very high data rate applications. Implementing system models and investigate algorithms for performance enhancements, design and validate them to allow performance sign-off and enable RTL development. Implementing system models for the wireless communication system and RF/circuits impairments. Defining the control procedures of the physical layer hardware modules to achieve robust and optimal performance of the Modem in a congested radio environment. Designing methods/ algorithms to alleviate those impairments by calibration, pre-equalization, cancellation, and/or pre-distortion techniques. Collaborating with digital designers to realize these methods with power and area efficient digital implementations. Collaborating with firmware designers to realize these methods with high efficiency software implementation and possibly with hardware acceleration. Bringing up, testing, characterizing and optimizing real silicon in the lab.
