Gurgen H. Khachatrian, Hamlet K. Khachatrian · Mathematical Problems of Computer Science · 2018
In this paper a construction of double ±1 and ±2 errors correcting linear optimal and quasi-optimal codes over rings Z5, Z7 and Z9 is presented with the limitation that both errors have the same amplitude in absolute value.
