    Hey guys,

    I'm trying to just generate some guassian white noise using the function awgn() in Matlab, but i keep getting the error:

    Code ( (Unknown Language)):
    1. ??? Undefined function or method 'awgn' for input arguments of type 'double'.
    :( Can somebody help me? I'm using Matlab student edition version 7.8

    - Andrew

    That usually means there is no function awgn() in the matlab toolboxes.

    Bummer, I discovered that the student version of matlab doesn't have the communications toolbox.

    So I just paid the $29 USD to add on the comms toolbox to the student version. =\ oww.. they should not be charging 30 bucks for every toolbox to students, I think...

    Anyway it works.
