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).

Lastly AWGN is added to simulate a typical receiver/thermal noise floor after propagation, and the variance may be modified here as desired. </doc> diff --git a/gr-channels/grc/channels_fading_model.xml b/gr-channels/grc/channels_fading_model.xml index 2b68cfa2ec..d47f0624f1 100644 --- a/gr-channels/grc/channels_fading_model.xml +++ b/gr-channels/grc/channels_fading_model.xml @@ -61,7 +61,7 @@ <type>complex</type> </source> <doc> - This algorithm implements the method described in + This algorithm implements the method described in Compact Rayleigh and Rician fading simulator based on random walk processes A.
