Orthogonal Frequency-Division Multiplex (OFDM) Waveform Optimized for Power Limited Line of Sight (LOS) User Environments
Agency / Branch:
DOD / NAVY
Kuma Signals proposes the DILLO fractional bit mapping framework with three candidate waveform designs to investigate in Phase I. The DILLO system is designed to enable orthogonal frequency division multiplexing (OFDM) in high Doppler, low SNR, long delay spread environments with impulsive noise. The framework utilizes an innovative holistic approach to the physical layer design, focusing on cancellation of inter-carrier interference combined with powerful channel coding and spreading for low peak-to-average power ratio reduction. The framework is designed to operate at SNRs of -20 to 0 dB and offer 4.8-64 kbps data rates under stressed conditions.
