    Abstract

    Using dually-polarized technology to double the spectral efficiency is very attractive in satellite communication systems. However, the cross polarization interference (XPI) which is inevitable will degrade the performance of the system. In order to eliminate it, a cross polarization interference cancellation (XPIC) is necessary, at least under unfavourable propagation conditions. This paper mainly studies the issue of cross polarization interference cancellation for dually-polarized radio systems over earth-space links. A joint XPIC and DEAF is presented, and compared with conventional XPIC, DEAF and other equalizer structures. The study shows that even under the circumstances with XPI only, the combination of XPIC and DEAF are necessary, for the XPI in the signal will cause ISI during the signal processing which can not be eliminated by the XPIC. And the simulation results also show that the joint XPIC and DEAF have the best performance among them. © 2011 Published by Elsevier Ltd.
