DSP Wireless Systems Engineer

In this technical role, you will be at the center of a silicon design group responsible for using digital algorithm or method to improve the PA efficiency, reducing power consumption, but with acceptable linearity for high data rate applications

• Design and simulate state-of-the-art wireless transmitter for very high data rate applications
• Investigate innovative PA architectures, calibration algorithms, processing structures for performance enhancement
• Architect HW/FW/SW partitioning of various calibrations for area and time efficiency
• Implement system models of the analog front-end design, impairments and come up with right controls and calibrations in C and MATLAB for optimal system performances
• 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 possibility hardware acceleration
• Bring up, test and characterize real silicon with relevant implementation in lab

• BS and a minimum of 10 years relevant industry experience
• Experience in designing relevant signal processing for wireless communications systems
• Understand the methods to estimate various RF impairments via direct equipment measurement or self-testing via loopback
• Experience with MATLAB or Python and/or C/C++ for algorithm development, modeling, and simulation
• Hands on experience on lab testing & characterization will be essential
• Some understanding of RF and analog components/modules composited of wireless communication systems
• Proven track record of optimization algorithm, and its applications to RF calibration
• Previous experiences on digital predistortion, crest-factor reduction, nonlinear crosstalk/interference cancellation, and real-chip bring-up in lab
