Re: [Discuss-gnuradio] SNR(Signal to Noise Ratio) Value in DQPSK Implementation

[waqasme]

Hi Tom,

Thanks for your reply. yah i did use noise block and i am changing the
amplitude in the noise block but it does not make any difference in the
output. You said calculate the SNR value i have to check signal power and
determine the noise power. i dont know how to calculate those values. iam
simply changing the amplitude in the noise block and try to see if it makes
any difference. And the link you have provided below is the C++ code that
does not explain anywhere how to calculate or change the SNR value. Can you
please explain in detail how it works. 
i really appriciate your help and support.

Thanks and Regards,

Waqas
