A simple polarization-recovery algorithm for dual-polarized cellular mobile-radio systems in time-variant faded environments

Dual-polarized signaling constitutes an effective frequency-reuse technique to enhance the cell capacity in cellular mobile-radio systems. In the pres ent paper, we present a new cross-polarization interference canceler (XPIC) which accomplishes the polarization-recovery task in time-division multipl e-access (TDMA)based cellular radio systems. The main new attractive featur e of the proposed XPIC is that it is able to work even in the presence of u nknown and possibly time-variant random phase fluctuations, as those due to imperfect phase recovery at the receiver side.
