Abstract
Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous communication frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming communication frames based on frame information extracted from previously received communication frames. For example, a remote unit can be configured to receive one or more communication frames, each of the one or more communication frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next communication frame. The remote unit can extract the payload data from the next communication frame based on the predicted value for the additional start-of-frame field.
