Elias-type Bounds for Codes in the Symmetric Limited-Magnitude Error Channel
Zhihao Guan, Hengjia Wei
We study perfect error-correcting codes in for the symmetric limited-magnitude error channel, where at most coordinates of an integer vector may be altered by a…

On Lattice Tilings of Asymmetric Limited-Magnitude Balls $\cB(n,2,m,m-1)$
Zhihao Guan, Hengjia Wei, Ziqing Xiang
Limited-magnitude errors modify a transmitted integer vector in at most entries, where each entry can increase by at most $\kp$ or decrease by at most $\km$. This channel model…
