commit 597b93798a804cde1783d6d2ab53b348d57c44cd
Author: Tom Rondeau <address@hidden>
Date:   Mon Jul 7 12:18:00 2014 -0400

    Removing trailing/extra whitespaces before release.
    
    We should be more careful about letting these into the code in the future. 
In emacs, we can use (add-hook 'before-save-hook 'delete-trailing-whitespace).

     The desired power delay profile and max doppler frequency may be provided 
to achieve the desired Ricean or Rayleigh fading scenario.   For center 
frequency and sample rate offset models, a gaussian random walk process is 
conducted for each.   The single sample step variance and maximum deviation for 
these two processes is specified and may be modified to simulate various 
desired stability effects.  Lastly AWGN is added to simulate a typical 
receiver/thermal noise floor after propagat [...]
