Check node processing

Non-binary low-density parity-check (NBLDPC) codes have a better error-correcting performance in comparison with their binary counterparts when the code length is moderate. However, NB-LDPC decoding is high complexity, especially the check node processing. In this paper, a novel check node processing algorithm and corresponding architectures are proposed for the trellis min-max NB-LDPC decoding to reduce the hardware complexity. A layered decoder architecture is implemented for the (2304, 2048) NB-LDPC code over GF(16) based on the proposed algorithm with a 90-nm CMOS technology.

The scripts provided as part of this paper are sample code which can be used to base your own scripts on. These scripts have been tested on an Oracle Enterprise Linux - 2 node cluster. It is expected that they should work on all Oracle Clusterware supported platforms. Oracle Support cannot provide any direct support for these scripts. You should thoroughly test the scripts – in particular the check action of each script to ensure compatibility with your operating system.

The ease or difficulty of packet snooping (also known as eavesdropping) on networks depends largely on the technology implemented. Shared media networks are particularly susceptible to eavesdropping because this type of network transmits packets everywhere along the network as they travel from the origin to the final destination. When concentrators or hubs are used in a shared media environment (such as FDDI, 10BASE-T, or 100-Mbps Ethernet), it can be fairly easy to insert a new node with packet-capturing capability and then snoop the traffic on the network.
