Constrained systems with unconstrained positions
We develop methods for analyzing and constructing combined modulation/error-correctiong codes (ECC codes), in particular codes that employ some form of reversed concatenation and w...

Classes of optical orthogonal codes from arcs in root subspaces
We present new constructions for (n, w, ) optical orthogonal codes (OOC) using techniques from finite projective geometry. In one case codewords correspond to (q - 1)-arcs contain...

High-rate codes with sublinear-time decoding
Locally decodable codes are error-correcting codes that admit efficient decoding algorithms; any bit of the original message can be recovered by looking at only a small number of ...

Tunnel_Sim: Decision support tool for planning tunnel construction using computer simulation
Tunnel construction are essentially infrastructure projects that includes many interfered and sophisticated tasks. This paper presents a decision support tool, Tunnel_Sim, for pla...

Expander Codes
Sipser and Spielman have introduced a constructive family of asymptotically good linear error-correcting codes--expander codes--together with a simple parallel algorithm that will ...
