摘要:
A transmitter selectively encodes or does not encode a data frame to be transmitted with an error correcting code depending on the congestion and occurrence of bit errors of a transmission path, and transmits the data frame with decision information indicative of whether the data frame has been encoded with the error correcting code or not for preventing either bit error or cell loss not. A receiver determines whether the received data frame has been encoded with the error correcting code or not based on the decision information sent with the data frame. The receiver decodes the data frame which has been encoded with the error correcting code, and outputs a decoded frame length, or delays the data frame which has not been encoded with the error correcting code for a delay time corresponding to the length of a preceding data frame and adds the data frame in a time series sequentially. The receiver then decodes the data frame into original data.
