Q-boson interferometry and generalized Wigner function
  Bose-Einstein correlations of two identically charged $Q$-bosons are derived considering these particles to be confined in finite volumes. Boundary effects on single $Q$-boson spectrum are also studied. We illustrate the effects on the spectrum and on the two-$Q$-boson correlation function by means of two toy models. We also derive a generalized expression for the Wigner function depending on the deformation parameter $Q$, which is reduced to its original functional form in the limit of $Q \to 1$.
