Abstract

Long BCH codes can achieve about 0.6-dB additional coding gain over Reed-Solomon codes with similar code rate in long-haul optical communication systems. BCH encoders are conventionally implemented by a linear feedback shift register architecture. Encoders of long BCH codes may suffer from the effect of large fanout, which may reduce the achievable clock… (More)
