P-LDPC coded image transmission with OFDM over underwater acoustic channel
Acta PolytechnicaUnderwater environment is still an attractive area to explore and exploit by human beings. However, underwater characteristics limit communications due to harsh channel conditions, and efficient channel codes are essential to deploy. This study presents

High throughput implementation of an adaptive serial concatenation turbo decoder
Journal of Communications Software and Systems, 2006 The complete design of a new high throughput adaptive turbo decoder is described. The developed system isprogrammable in terms of block length, code rate and modulation scheme, which can be dinamically changed from frame to frame, according to varied ...

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, EarlyView.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Turbo Codes Performance Optimization over Block Fading Channels
Journal of Communications Software and Systems, 2006 In this paper, the best achievable performance of a turbo coded system on a block fading channel is obtained, assuming binary antipodal modulation. A rate 1/3 turbo code is considered, obtained by concatenating, through a random interleaver, an 8-states ...

, 2006 92 p. Since the discovery of Turbo Codes in 1993, it has became clear that the real limit on communication rate was not set by Shannon's Capacity Theorem but by the complexity of the coding schemes and its cost of implementation. In recent years much research has been directed towards finding efficient and practical coding schemes.

The FEBS Journal, EarlyView.Iduronate 2‐sulfatase (IDS; purple) is expressed as a precursor protein that goes through multiple steps of maturation, modification, and trafficking to become an active lysosomal enzyme that degrades glycosaminoglycans. Our study shows that the transmembrane ubiquitin ligases RNF13 (orange) and RNF167 (pink) heterodimerize, affecting IDS intracellular

Automodification of N‐terminal serine residues facilitates PARP2 release from DNA
The FEBS Journal, EarlyView.PARP2 is involved in detecting DNA damage and its N‐terminal role is largely unknown. Based on biochemical and biophysical data, our findings suggest that in the presence of HPF1, N‐terminal serine 8 and 73 are enriched in auto‐ADP‐ribosylation. Our results provide insight into the mechanistic role of PARP2 N‐terminus in the PARylation‐dependent ...
