SPECTRA · COMINT Signal Analysis Workbench

Smart India Hackathon 2026 · PS 26147 · blind analysis of .wav / .iq intercepts - every parameter is measured from the samples

This page shows results computed by the SPECTRA receiver on the five bundled ground-truth captures (precomputed, not a live upload). The interactive tool is the desktop app - source & download on GitHub.

BER vs Eb/N0 - measured through the full receiver

Dashed = uncoded QPSK theory. Hollow marker = some frames lost at that point (receiver lock failure, excluded from BER). Down-triangle = no errors seen (plotted at 1/bits tested).
