You will have an opportunity of designing and innovating the algorithms and architectures of wireless communication systems, working with the world class RF/analog, HW, SW designers, architects, implementing, verifying, validating and bringing up the SoC products to the production quality, providing them to millions of Apple customers. Core Responsibilities includes but not limited to the following. Design and simulate state-of-the- wireless communication system for very high data rate applications. Implement system models and investigate innovative algorithms for performance enhancements, design and validate them to allow performance sign-off and enable RTL development. Implement system 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. Define the control procedures of the physical layer hardware modules to achieve robust and optimal performance of the Modem in congested radio environment. Work with digital designers to realize these methods with power and area efficient digital implementations. Work with firmware designers to realize these methods with high efficiency software implementation, and possibly with hardware acceleration. Bring up, test, characterize and optimize real silicon in lab.**Education & Experience**MS with 5+ Years experience or Ph.D. with 3+ Years experience.**Additional Requirements****Apple Footer**Apple is an equal opportunity employer that is committed to inclusion and diversity.
