Polar Coding Without Alphabet Extension for Asymmetric Models
TLDR
A new polar coding scheme for asymmetric settings that can attain the channel capacity without any alphabet extension by invoking results on polar coding for lossless compression. Expand

Asymptotic performance of a modified Schalkwijk-Barron scheme for channels with noiseless feedback (Corresp.)
TLDR
A modified Schalkwijk-Barron transmission scheme is presented for channels with noiseless feedback in place of Viterbi's sequential decision feedback. Expand

Secret sharing system using (k, L, n) threshold scheme
In the (k, n) threshold scheme, the information X is partitioned and coded into subinformation. If any k subinformation is obtained among n subinformation, the original information X can be recovered… Expand

Private information retrieval for coded storage
TLDR
We propose a class of linear storage codes and retrieval schemes and derive conditions under which our schemes are error-free and private. Expand

Viterbi decoding algorithm for convolutional codes with repeat request
TLDR
Using the Viterbi decoding algorithm with repeat request for convolutional codes is proposed, and the resulting performance is analyzed by random coding and generating function arguments and simulation. Expand

Asymptotic properties on codeword lengths of an optimal FV code for general sources
TLDR
This correspondence is concerned with asymptotic properties on the codeword length of a fixed-to-variable length code (FV code) for a general source {X/sup n/}/sub n=1//sup /spl infin// with a finite or countably infinite alphabet. Expand

Quantum secret sharing schemes and reversibility of quantum operations
Quantum secret sharing schemes encrypting a quantum state into a multipartite entangled state are treated. The lower bound on the dimension of each share given by Gottesman [Phys. Rev. A 61, 042311… Expand
