Re: [Discuss-gnuradio] how to measure ber and snr

[Marcus Müller]

Hi BZS,

haven't seen you in a long time! Welcome back :)

If you use the search tool in gnuradio-companion, you will find the BER block, which has two inputs and will output an BER measurement.

SNR is highly dependent on what you consider to be signal and what you consider to be noise, so for most cases you will have to make your own Signal Power measurement and divide that by a noise power estimate.

Greetings,
Marcus
