Abstract :
Efficient algorithms are derived for maximum likelihood (ML) soft-decision decoding of some binary self-dual codes. A family of easily decodable self-dual codes is derived by modifying a known F24, which has a weight distribution resembling that of the [24, 12, 8] Golay code G24. The ML decoding of F24 is accomplished by only 227 real additions, compared to 651 required for G24, yet the error rates of the two decoders are similar for moderate noise conditions
