Title:  Massive MIMO Principal System Engineer

Everyone communicates. It’s the essence of the human experience. How we communicate is evolving. Technology is reshaping the way we live, learn and thrive. The epicenter of this transformation is the network—our passion. Our experts are rethinking the purpose, role and usage of networks to help our customers increase bandwidth, expand capacity, enhance efficiency, speed deployment and simplify migration. From remote cell sites to massive sports arenas, from busy airports to state-of-the-art data centers— we provide the essential expertise and vital infrastructure your business needs to succeed. The world’s most advanced networks rely on CommScope connectivity.

 

Currently, we are looking for a Principal System Engineer for our site in Agrate. This position is responsible for development of Beamforming and Massive MIMO radio system architectures for existing 4G wireless standards and developing 5GNR systems.

 

Duties include:

 

  • Define and capture wireless product performance, interfaces, and environmental requirements.  Interpret wireless standards and plays a key role in product requirements formulation.
  • Define calibration strategy, techniques and algorithms for Active Antenna Arrays. Perform analysis and simulation of proposed algorithms using Matlab/Simulink in order to ensure required beamforming performance.
  • Contribute to product architecture and partition functions to sub-assemblies, including optimization of functional partitioning between DSP, mixed signal, and RF sub-sections. Allocate and document the requirements of product sub-assemblies.
  • Perform analysis and simulation of RF chain, MIMO, and beamforming behavior from baseband through the antenna, including CFR and DPD to appropriately scale power amplifier and antenna characteristics. 
  • Conduct trade studies and analyses to optimize product cost, size, weight, and power consumption while meeting requirements with adequate margin for high yield in production.
  • Define the product DVT, engineering test, and production test requirements, with specific focus on Over-The-Air tests for beamforming validation.

 

Qualifications:

  • Experience in active and adaptive beamforming RF systems.
  • Experience with Antenna Array calibration techniques for digital beamforming technology.
  • Experience with linearization techniques for power amplifiers.
  • Familiar with digital signal processing algorithms for 4G/5G wireless transceivers, including lower PHY processing.
  • Experience with Matlab/Simulink tools.
  • Understanding of receiver and transmitter functional blocks and capabilities including antennas, power amplifiers, filters, duplexers, oscillators, frequency converters, modulators, and demodulators. Understanding of corresponding impairments (thermal noise, phase noise, non-linearities, PIM, group delay, intermodulation, spurious) and impacts.
  • Experience in link budget analysis, chain analysis, EVM analysis, and throughput analysis.
  • Experience in analyzing high level system requirements to extract block level hardware and software level requirements.
  • Knowledge of wireless infrastructure architectures and air interface standards including LTE and 5GNR.
  • Skilled in thorough documentation of requirements and architectures and presentation of radio architecture concepts.
