Naming convenction of random variables in spectral representation

[mbvoyager]

Samples of stochastic processes generated using spectral representation are now all labeled by the symbol :gm.

This results in the naming of the collection of generated signals (stochastic processes) as gm and the random phase angles as gm_1, gm_2, gm_3, ....
This is confusing. Since at least for spectral representation only the phase angles ϕ are the random variables, I think it would be better to name and number them as ϕ_1, ϕ_2, ϕ_3, ...
