A unary error correction code for the near-capacity joint source and channel coding of symbol values from an infinite set [PDF]

open access: yes, 2013
A novel Joint Source and Channel Code (JSCC) is proposed, which we refer to as the Unary Error Correction (UEC) code. Unlike existing JSCCs, our UEC facilitates the practical encoding of symbol values that are selected from a set having an infinite ...

Channel Coding for Power Line Communication Based on Oversampled Filter Banks

open access: yes, 2005
Oversampled filter banks (OSFB) can be applied as channel coding and have shown benefits in correlated and impulsive noise. Therefore, in this paper, we consider such channel coders for a power line communications scenario, where such conditions create a

Near-capacity dirty-paper code design : a source-channel coding approach

open access: yes, 2009
This paper examines near-capacity dirty-paper code designs based on source-channel coding. We first point out that the performance loss in signal-to-noise ratio (SNR) in our code designs can be broken into the sum of the packing loss from channel coding ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Near-capacity cooperative space-time coding employing irregular design and successive relaying [PDF]

open access: yes, 2010
In this paper, we develop a capacity-approaching Cooperative Space-Time Coding CSTC scheme employing irregular design for a twin-relay aided network as an extension of our previous work cast in the context of a half-duplex single-relay-aided network. For
