Title: DSP / Digital Communications Engineer

Location: Herndon VA - remote work is available

Type: Full-time Permanent

Notes: This is 90% theoretical 10% implementation

Responsibilities

• Designing and testing DSP-based, high speed FPGA designs


• Designing and supporting top-level digital communication design and system simulations


• Translating requirements into FPGA/waveform architectures


• Implementing and documenting FPGA designs using HDL (System Verilog, VHDL, etc.)


• Supporting systems integration and Test Engineering to produce functional design


• Producing simulations of and designs for both channel improvement measures, such as spectral bandwidth efficiency, and user density improvement measures, such as interference mitigation/cancellation, multiuser detection, and phased array antenna techniques


• Designing the implementations for further advances in adaptive TDMA, SCPC return channels.


• Designing and the implementation of anti-jam DSP techniques implemented in FPGA logic.


• Writing internal and external facing documents about iDirect Government physical layer FPGA technology

Qualifications

• FPGA design experience using Verilog, VHDL or System Verilog language targeting Xilinx/Altera FPGA's


• Knowledge of DSP and digital communications. Understanding of time domain versus frequency domain analysis, filter structures, and modulation/coding algorithms. Ability to describe and architect trade-offs for resource-limited systems.


• Experience Matlab/Simulink or equivalent for development of DSP algorithms implemented in FPGA's


• Ability to plan/perform analysis, studies/trade-offs in support of subsystem specification and hardware, FPGA, and software design recommendations.


• Experience in RF lab, including network setups (switches, cables, amplifiers, and filters) and signal analysis (Spectrum Analyzers, Network Analyzers, signal generators, etc.)


• Additional experience in the following areas is a plus:


• Experience with digital communications and control theory - stability and feedback control
