Group 66-Summer Research Program Intern

Date: Mar 9, 2023

Location: Lexington, MA, US

Company: MIT Lincoln Laboratory

MIT Lincoln Laboratory, located in Lexington, Massachusetts, is a federally-funded research and development center (FFRDC) chartered to apply advanced technology to problems of national security. The Laboratory provides technical expertise, prototype development, and technology transfer to the US government in domains ranging from cybersecurity to novel radar design to advanced microelectronics, and more.


The Advanced Lasercom Systems and Operations Group develops, builds, tests, and operates laser communications systems for a variety of applications and environments. Lasercom offers dramatically increased data rates and enhanced physical security relative to standard radio frequency-based communications systems. The Group has expertise in communications; optics; electro-optics; optical turbulence mitigation; precise pointing control systems; embedded systems; command, control, and telemetry; test set design and fabrication; data analysis; modeling; and simulation.

Job Description:

The Advanced Lasercom Systems and Operations Group is seeking summer interns to develop low cost, software-defined, free-space optical communications modems. The selected candidate(s) will work with hardware, software, and systems engineers to architect, implement, test, and validate the SDR modem. Once validated in the laboratory, the modem will be replicated, and the two modems will be deployed on an outdoor free-space optical test range for field validation. Once validated, the SDRs modems will be used to collect lasercom field data for future publications.

Job Requirements:

The group is seeking candidates with experience and expertise in developing software defined radios (SDRs). Specifically, interns will be using Universal Software Radio Peripheral (USRP) units to implement and demonstrate transmit and receive modem functionality. Other requirements include familiarity with:

  • GNU Radio and its usage for implementing software-defined radios
  • Interfacing USRPs with MATLAB for hardware-in-the-loop testing
  • Test and verification equipment to validate and characterize radio performance

Required Skillset:

  • Programming expertise in C/C++, and Python, to develop software-defined radios
  • Proficient in Linux-based development environment
  • MATLAB experience for simulation and hardware-in-the-loop testing
  • Basic familiarity with communication theory, modulation formats, and radio performance characterization

Desired Skillset:

  • Familiarity with computer architecture, operating systems, and parallel computing
  • Familiarity with using GPUs for implementing software-defined radios
  • Understanding of networking, socket programming, and troubleshooting
  • Experience with free space optical communication systems

Selected candidate will be subject to a pre-employment background investigation and must be able to obtain and maintain a Secret level DoD security clearance.
