Abstract
By using multiantenna diversity system to combat fading for mobile rec eption of video signals a nearly omnidirectional antenna pattern diagr am can be achieved. However ghosts, especially fluttering ghosts, main ly caused by the fast rotating echo phases and RF signal level fluctua tion, affect still the picture quality. II is shown that a single GCR- signal is not sufficient for the fluttering ghost suppression. A blind TV signal equalisation algorithm, which is based on image processing techniques, is developed to remove interference of echoes with rapidly changing phases. A simplified version of this algorithm is included t o reduce the computational load and allow suitable IC integration.
