Generalized Bicycle Codes with Low Connectivity: Minimum Distance Bounds and Hook Errors
Reza Dastbasteh, Olatz Sanz Larrarte, Arun John Moncy +3
We present new upper and lower bounds on the minimum distance of certain generalized bicycle (GB) codes beyond the reach of techniques for classical codes capable of even capturing…
