Apparatus and method for low density parity check code decoding in a first processing device, wherein the method includes receiving a first bit-word of a first length related to a log-likelihood ratio of a bit of a signal; obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word; and determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit-word.

Apparatus and method for low density parity check code decoding

Devices, methods and computer programs for accelerating low-density parity-check (LDPC) decoding via scheduling are disclosed. At least some of the example embodiments described herein may allow reducing cost and improving power efficiency beyond that of semiconductor processor scaling currently used in accelerating LDPC decoding.

Various example embodiments for supporting forward error correction (FEC) in a communication system are presented. Various example embodiments for supporting FEC in a communication system may include selection of a FEC setting (e.g., an amount of puncturing and/or shortening of a FEC code, a FEC code, or the like) for a communication channel from a transmitter to a receiver based on channel characteristic information of the communication channel from the transmitter to the receiver (e.g., transfer function information, channel loss information, noise characteristic information, error information (e.g., bit error rate, error modeling, or the like), or the like). Various example embodiments for supporting FEC in a communication system, based on selection of a FEC setting for a communication channel based on channel characteristic information of the communication channel, may be applied within various types of communication systems, including various types of wired and/or wireless communication systems.

Forward error correction

Systems for transmitting information from terminal systems () via access multiplexers () comprising virtual forwarder systems () to networks are made less complex by inserting at the terminal systems () virtual forwarder internet protocol addresses () into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses () into routing fields of the internet protocol headers. Both the terminal systems () and the access multiplexers () should be made capable of dealing with internet protocol headers of the internet protocol version-4 or the internet protocol version-6 or higher, which comprise a destination field and a routing field. The destination internet protocol addresses () in the routing fields allow distinguishment between different classes of services and/or applications used by the terminal system () simultaneously, without the access multiplexers () being obliged to unpack (parts of) the information and to detect (parts of) the information at higher layers.
