Key Responsibilities- Design and simulate state-of-the-art wireless transmitters for very high data rate applications.
- Investigate innovative PA architectures, calibration algorithms, and 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 (such as spectrum analyzer, signal generator, signal analyzer, power meter, etc.).
- Some understanding of RF and analog components/modules composited of wireless communication systems, the possible impairments from those components, their impact to OFDM signals, and the corresponding calibration and impairment reduction methods/algorithms.
- MSEE/PhD with relevant experience.
- 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.
- Understand communication theory & signal processing related algorithms design (such as timing recovery, signal estimation and detection, automatic gain control, channel estimation, equalization, coding theory, etc.).
- Knowledge in existing wireless communication protocols: 5G-NR/LTE/WCDMA/GSM, WiFi, and/or Bluetooth/BLE.
- Course works and experience in circuit design.
