Abstract
The encoder of a communication device is configurable such that the encoder may operate in any of a variety of forward error correction modes. Further, for each mode, a variety of encoding parameters may be configured. The configurability of forward error correction modes and/or parameters enables communication devices to perform interactive configuration processes, whereby a communicating device specifies the type of forward error correction that the other is to perform. This configuration may be bidirectional, such that each device selects the forward error correction provided by the other. Each device may further configure its decoder to decode the forward error correction mode that it has selected for the other communication device. In other embodiments two communicating devices may implement two different modes of forward error correction.
