Lead, Electrical Engrg

L3Harris
Palm Bay, FL 32907
Description:

This position will be responsible for analytical support to an advanced modem design team. Areas of analysis include traditional communications modulations in the satellite communications domain providing Digital Signal Processing (DSP) Analysis for customer-funded programs and internal research efforts within our Communication Systems (CS) Segment.

L3Harris Communication Systems segment provides integrated solutions for U.S. and international defense and public safety networks, including tactical communications, broadband communications, night vision technology, and public safety. We specialize in advanced Satellite Communications waveforms, SATCOM terminals and modems, and various other specialized communications systems.

The experienced DSP/Communications Analyst will perform the following:

  • Derive link budgets and transmitter/receiver analysis for signals operating at near-threshold levels through ground terminals and satellite transponder
  • Construct, modify, and run MATLAB simulations for complex waveforms to derive performance requirements and expectations for Bit Error Rate (BER) in additive white Gaussian noise (AWGN) and jamming, and detection of LPD signals
  • Architect Communication systems including terminals and modems implementing algorithms such as advanced modulation schemes, automatic gain control (AGC) design and control, forward error correction, time and frequency tracking, signal excision
  • Work closely with the engineering teams through design, implementation, integration, and test of the signal processing and communication subsystems; support the complete testing and qualification of the deliverable system

    Qualifications:

    • PhD Degree in Mathematics, Physics, Electrical Engineering, Computer Science, or Computer Engineering and minimum 9 years of prior relevant experience
    • Minimum of 7 years’ experience with Digital Signal Processing operations and optimization (FFT, FIR filters, Up/Down sampling, modulation, convolution, and correlations)
    • Minimum of 7 years of experience with modem signal processing in areas such as coding, pulse shaping, symbol mapping, tracking loop design, equalization, multirate, and digital translation

      Preferred/Additional Skills:

      • Solid understanding of Digital Signal Processing concepts
      • Solid understanding of Communication theory with experience generating Signal Processing models and Communication models using MATLAB
      • Experience with Broadband networking Ethernet Layer 2 and 3 implementation
      • Experience with RF design impairments, including simple cascaded analysis and link budget analysis
      • Experience with advanced waveforms including spread spectrum, Orthogonal Frequency-division Multiplexing (OFDM), Low Probability of Intercept/Low Probability of Detection (LPI/LPD), Anti-Jam (AJ)
      • Experience with chaotic signal processing methods and chaotic sequence spread spectrum modulations
      • Experience with advanced signal detection processing techniques including radiometric methods, higher order statistical analysis, cyclostationary signal processing and other time frequency transforms, and other relevant statistical signal processing detection techniques such as wavelet transforms and eigendecomposition/ Principal Component Analysis (PCA)

        Security Clearance:

        This position requires an active DoD Secret security clearance.
