On the Zero-Error Capacity Threshold for Deletion Channels
—We consider the zero-error capacity of deletion channels. Specifically, we consider the setting where we choose a codebook C consisting of strings of n bits, and our model of t...

Secure communications with insecure feedback: breaking the high-SNR ceiling
A multiple-antenna Gaussian wiretap channel in which the number of antennas at the source is not greater than that at the eavesdropper is considered. Without feedback, the secrecy...

Hardware architectures for successive cancellation decoding of polar codes
The recently-discovered polar codes are widely seen as a major breakthrough in coding theory. These codes achieve the capacity of many important channels under successive cancella...

Fast zeta transforms for lattices with few irreducibles
We investigate fast algorithms for changing between the standard basis and an orthogonal basis of idempotents for M¨obius algebras of finite lattices. We show that every lattice...
