Does anyone know what the distribution of the sum of squared Nakagami is? $$\sum_i^n X_i^2$$ $$X_i\sim \text{Complex Nakagami-m }$$
Is the distribution Erlang? Is the distribution the same as
$$\big|\sum_i X_i \big|^2 $$ or $$\big(\sum_i X_i \big)^2 $$ If the distribution of the above are not the same, do you know under what conditions they have the same distribution?
Cheers!
