摘要：A receiver is arranged to start receiving a data frame including application datafollowed by parity data. An erasure information table is generated, and includes oneelement for each element of a data frame . If there are no errors in the application data,the receiver is powered-down to sleep without receiving the parity data, and the

application data is used without correction being needed. If the number of errors in theapplication and parity data exceeds the MPE-FEC correction capability, the receiver ispowered-down to sleep without further parity data being received and the data is notdecoded. If the number of errors is smaller than the MPE-FEC correction capability, thereceiver is powered-down to sleep when sufficient parity data is received to correcterrors in the application and parity data. This can save power in the receiver. In anotherembodiment, the erasure information table includes one element for each column of adata frame.
