A 105 Mbit/s Error Correcting Codec

A 105 Mbit/s experimental error correcting encoder/ decoder is described. The device exhibits a coding gain of 1.9 dB at a 10
^-5
bit error rate and has a 25 percent parity bit overhead. The decoder was constructed without syndrome reset. This allowed the operating speed to be more than doubled, while only sustaining a negligible loss in performance.
