Well, I found the following: $$ H(z)=\frac{p z \sin(\alpha)}{z^2-2p z \cos(\alpha)+p^2} $$ I then tried to adjust the transfer function. First I did that for the denominator and found it had a pair of complex conjugate poles $0.8e^{+j\frac{3\pi}{4}}$, and $0.8e^{-j\frac{3\pi}{4}}$.The inverse bilateral Z transform provides the map from Fourier space back to state space, and allows one to recover the original sequence in applications of the bilateral Z transform.
