FORWARD ERROR CORRECTION WITH CHANNEL ADAPTATION

摘要

A transmit-configuration mechanism (52) for configuring an FEC encoder (34) (including an associated interleaver (84)) for changing data channel characteristics. Channel information specifying a modulation mode and carriers capable of supporting the modulation mode for the data channel is received by a transmitting network node (12a) for use in a data transmission to a receiving network node (12b). The received channel information is based on a prior data transmission to the receiving network node (12b) over the data channel. Configuration values are computed from the received channel information and an amount of data to be transmitted in a data transmission. The FEC encoder (34) is configured to operate on the data transmission data amount according to the configuration information.
