    This paper presents performance analysis of dual‐polarized M‐ary Quadrature Amplitude Modulated (QAM) signals over nondispersive radio channels. In particular, dual‐polarized, 16‐QAM signals are examined. A simple method for adaptive cancellation of static and fade‐induced cross‐polarization interference is introduced. The cancellation is performed at baseband. For this canceler, two adaptation methods are studied. The results indicate that dual‐polarized M‐ary QAM is not feasible over fading channels unless means of adaptive cancellation of the cross‐polarization interference are provided. The results also indicate that the adaptive algorithm employed in cross‐polarization interference cancellation should take into account noise power reduction.
