Bits - symbols mapping in M-PAM beginner question

I am trying to implement a M-PAM modulator in Matlab without using the built-in functions. I am confused when it comes to the symbols-bits mapping. Say I have a sequence of bits: ...

Determine minimum distance between two symbols in 16-QAM using the average symbol energy

If the probability of bit error for a square M-ary QAM is $P_M = (1-(1-P_\sqrt{M})^2)$ where $P_\sqrt{M} = 2(1-\frac{1}{\sqrt{M}})Q(\sqrt{\frac{3E_s}{(M-1)N_0}})$ and $E_s$ is the average symbol ...

How do I set GNU Radio Es/No?

I am trying to create a random signal in GNU Radio (using DVB-S2 specs for the physical layer) and transmit this signal using a USRP X310. This is shown below: Problem: I would like to be able to ...
Calculating $E_b/N_0$ from given SNR ratio
I have the following formula: $$\frac{S}{N}=\frac{E_b \cdot R_b}{N_0 \cdot B }$$ Where $S/N$ is of course SNR in dB, $E_b$ is energy per information bit, $R_b$ is information bit rate in [bit/s], \$...
