Summary: | By using multiantenna diversity system to combat fading for mobile reception of video signals a nearly omnidirectional antenna pattern diagram can be achieved. However ghosts, especially fluttering ghosts, mainly caused by the fast rotating echo phases and RF signal level fluctuation, still affect the picture quality. It is shown that a single ghost cancelling reference (GCR)-signal is not sufficient for fluttering ghost suppression. A blind TV signal equalisation algorithm, which is based on image processing techniques, is developed to remove the interference of echoes with rapidly changing phases. A simplified version of this algorithm is included to reduce the computational load and allow suitable IC integration. |
