Messages from the Past

Can you hear the echoes of history?

The 10th IEEE SB Karlsruhe Signal Intelligence Challenge – Messages from the Past – is here! A forgotten archive has yielded a trove of historical radio transmissions, riddled with challenges for the modern signal intelligence analyst. These aren’t clean, textbook signals; they’re degraded by decades of atmospheric noise, interference, and deliberate obfuscation. Your mission: recover these faint whispers from the past, decode their hidden messages, and piece together the stories they tell. Expect to encounter a diverse range of modulation schemes, potentially including legacy formats and custom encoding techniques, all buried within complex signal environments. This challenge will demand precision, ingenuity, and a deep understanding of signal processing fundamentals.

Test your skills in SDR, modulation, and data recovery. Compete for recognition and prove your mastery of signal intelligence.
