APPARATUS AND METHOD FOR PROVIDING OPTIMAL ADAPTIVE FORWARD ERROR CORRECTION IN DATA COMMUNICATIONS

摘要

An adaptive and dynamic forward error correction scheme for a communicationchannel is disclosed. The method and apparatus calculates (206) the actual biterror rate for comparison (207) with a target bit error rate. When a channelis performing better than required by the performance specification, theforward error correction power can be reduced (214) to provide greaterthroughput. If the calculated actual bit error rate is greater than the targetbit error rate, then the forward error correction power is increased (219) inan attempt to lower the calculated bit error rate. A feedback loop is employedto continually calculate received bit error rates as the forward errorcorrection power is increased or decreased.
