The Performance of Focused Error Control Codes
Consider an additive noise channel with inputs and outputs in the field GF (q ) where q > 2; every time a symbol is transmitted over such a channel, there are q - 1 different errors that can occur, corresponding to the q ...
A Generalized Gilbert-Varshamov Bound Derived via Analysis of a Code-Search Algorithm
This correspondence derives a generalization of the Gilbert- Varshamov bound that is applicable to block codes whose codewords must be drawn from irregular sets; the bound improves by a factor of four a similar result ...
A Communication Channel Modeled on Contagion
We introduce a binary additive communication channel with memory. The noise process of the channel is generated according to the contagion model of George Polya; our motivation is the empirical observation of Stapper et. ...
