At a Glance

Orthogonal Frequency Division Multiplex (OFDM) has attracted a lot of attention in civil and military communications in recent years. Due to its growing dissemination the reconnaissance of OFDM signals is becoming more and more important.

The universal OFDM demodulation toolkit has been developed for the analysis and processing of OFDM signals. The OFDM demodulator is a tool, which is fully configurable to process almost all types of OFDM signals.

Features

  • Application for offl ine demodulation of OFDM-signals
  • Processing of bursted and continuous signals
  • Absolute or differential demodulation (arbitrary constellations
  • Different constellations for each carrier possible
  • Alternating carrier constellation in OFDM-signal supported
  • Sampling rate error correction
  • Time and frequency synchronization
  • Channel equalization
  • Editing of burst detection results
  • Response to events (e.g. changing of demodulator configuration
  • Input signal file formats WAV and Matlab MAT supported
  • File output (Matlab MAT and raw binary), Demodulated symbols, IQ-values, Quality etc.
