feature/cavity_noise_simulation (additive noise implementation)

[ehtkarim]

The processor "gaussian-noise-generator" (from KTGaussianNoiseGenerator.cc) now correctly adds White Gaussian Noise to the signal. I've added an example config file (named KatydidPSConfig_noise.yaml) demonstrating the processor usage. One can also use a random number seed using the "seed" parameter in the config file

• KTGaussianNoiseGenerator

  • Has a working random seed feature now
  • Can configure noise-psd-floor values. Defaults to 2.2e-13 W/Hz (default CCA scenario)

• KTCavityNoiseGenerator

  • Inherited from KTGaussianNoiseGenerator
  • Has a working random seed feature now
  • Implements Wouter/Arina's frequency dependent cavity noise model
  • Can configure model parameters in the Katydid config file

• KTMeasuredNoiseGenerator

  • Inherited from KTGaussianNoiseGenerator
  • Takes a .yaml file with psd-mean and psd-variance values at different frequencies as input, interpolates them using a 3rd order spline, and implements the psd-mean and psd-variance values per frequency bin to generate noise

  I'm attaching some freq. and time slices with each of the three noises applied to a nominal 90 degree Locust_MC signal:
