AWGN generator blockin system generator

[verylsi]

Hi all,

I am looking for additive white Gaussian noise generator . I found that the LogicCore is discontinued by xilinx.
I would like to try using system generator , but my matlab version seems incompatible with system generator.
Can anyone help me some ways , how can I add WGN to my signal and verify it whether its right or not ?

Thanks

What frequency band do you need? Applied Instruments (www.appliedin.com) makes a couple of relatively low cost wideband WGN generators that can be added to your signal using a simple combiner.
