Echoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes. The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs. Echoes doesn't demodulate neither decode any human-made signal.

This utility 'rtl_sdr_panorama.exe' designed for panoramic imaging spectrum REALTIME any (reasonable) band by accumulating within 0.5 second spectral samples of limited bandwidth for simultaneous monitoring (speed via USB, usually within 2...3 MHz) c DVB- chip based RTL-2832/R820 (13...1864 MHz). Controlled parameters: 1. Dongle Phone system. 2. Initial scan, Hz. 3. Endpoint scan, Hz . 4. Spacing scanning ediitsy tens kHz/MHz. 5. Noise level, dB. 6. Magnitude clock frequency correction, ppm. ...

This program is designed to determine the correct parameters of a model atmosphere of a star through iterative refinement and measurements of spectral absorption lines. **Correction: It appears that what I termed "iterative refinement" has already been named "Predictor-Corrector" by the Mathematical Community.** Regrettably, this program still depends on a few other programs, namely SuperMONGO (http://www.astro.princeton.edu/~rhl/sm/sm.html though this page is fairly old, you may need to purchase SM) and MOOG (http://www.as.utexas.edu/~chris/moog.html). ...

An Educational Toolbox on Data Communications, including Encoding Schemes, Bit-Error-Rate (BER), Noise and Spectral Analysis for Scilab

...A new modulation method 'Advanced PCC-OFDM' is developed. With this method you can construct a modulation, which is fast decaying in frequency domain, while maintaining spectral efficiency.
