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 communication channel is disclosed. The method and apparatus calculates (206) the actual b it error rate for comparison (207) with a target bit error rate. When a channel is performing better than required by the performance specification, the forward error correction power can be reduced (214) to provide greater throughput. If the calculated actual bit error rate is greater than the targ et bit error rate, then the forward error correction power is increased (219) i n an attempt to lower the calculated bit error rate. A feedback loop is employ ed to continually calculate received bit error rates as the forward error correction power is increased or decreased.
