gr-inspector
Out-of-tree GNU Radio module available in GNU Radio World
gr-inspector is a signal-analysis toolbox for finding and characterizing unknown activity in wideband complex sample streams. Its energy detector builds an RF map of occupied regions, and its separator shifts and filters every detected region before an extractor turns a selected message-bundled signal back into a conventional stream at an optional fixed sample rate. For OFDM signals, a parameter estimator searches likely FFT and cyclic-prefix lengths, while a companion synchronizer corrects fine frequency offset and tags the estimated symbol boundaries for downstream processing.
