Re: MPSK SNR Estimator

[Marcus Müller]

Ok, context, please. Where do you want to use it? As the MPSK SNR estimator block 
documentation says:

>  It copies the input stream to the output stream, but adds a tag that contains the 
estimated SNR every N samples

So, generally, you read the tag using a downstream block. This might or might not be the 
thing you're looking for! So, could you please tell us in which way you want to use the 
SNR estimate?
