Method and apparatus for detecting simulcast channel conditions |
摘要 |
A circuit (350) for detecting simulcast channel conditions includes a symbol center averaging circuit (308) for providing a center count of excursions above and below at least a first predetermined threshold and for providing a moving average of the center count over a predetermined number of symbol periods and a symbol edge averaging circuit (310) for providing an edge count of excursions above and below at least a second predetermined threshold and for providing a moving average of the edge count over a predetermined number of symbol periods. Finally, the circuit further includes a comparison circuit (360) programmed to receive and compare the moving average of the center count and the moving average of the edge count to provide a control signal (380) for simulcast detection.
