Hello,

When writting a gamma distributed RV we need to know the shape and scale parameters. How to find the value of these parameters?

What do you mean by find these parameters? Do you wish to estimate the parameters of a gamma distribution from some data?

No, I meant if we are given the equation of the gamma distributed RV, how to find these parameters from this equation? Mathematically:
$$\gamma = \frac{\|\mathbf{h}\|^2P}{N_0}$$
where $$\mathbf{h}$$ is a column vector of Nakagami-m distributed RVs. Then how to find the scale and shape parameters from this equation?
