how to find snr

How to convert signal to noise ratio in terms of bit to signal to noise ratio in terms of symbol?

Divide the SNR in symbol by the bits per symbol.

Hi cwjcwjcwj

I suppose you want to relate Eb/No with Ps/Pn (signal-to noise ratio).

Eb = Ps/Tb = Ps*BR
No = Pn/BW

where

Tb = bit time
BR = bit rate [bps]
BW = noise bandwidth over which the noise power is measured

Then............ Eb/No = (Ps/Pn)*Tb*BW
