Delay constrained minimum energy broadcast in cooperative wireless networks
—We formulate the problem of delay constrained energy-efficient broadcast in cooperative multihop wireless networks. We show that this important problem is not only NPcomplete, ...

Almost-Certainly Runlength-Limiting Codes
Standard runlength-limiting codes – nonlinear codes defined by trellises – have the disadvantage that they disconnect the outer errorcorrecting code from the bit-by-bit likeli...

Low-distortion embeddings of general metrics into the line
A low-distortion embedding between two metric spaces is a mapping which preserves the distances between each pair of points, up to a small factor called distortion. Low-distortion...

Improved Nearly-MDS Expander Codes
A construction of expander codes is presented with the following three properties: (i) the codes lie close to the Singleton bound, (ii) they can be encoded in time complexity that ...

Improved upper bounds on sizes of codes
Let ( ) denote the maximum possible number of codewords in a binary code of length and minimum Hamming distance . For large values of , the best known upper bound, for fixed , is t...
