The symbol error rate was very high at 45.5% which might be the most errors ever corrected by EbNaut. With about 50% of the symbols correct just by chance, the signal was strong enough to bias the noise in favour of a further 4.5% of symbols. Certainly the highest list rank ever decoded. The high BER and high Eb/N0 are a symptom of the high CRC overhead. -- Paul Nicholson --
