    Abstract: An apparatus is provided for decoding a Low-Density Parity Check (LDPC) code in a communication system. In the LDPC decoding apparatus, an edge memory stores a message delivered through an edge between a variable node and a check node. A node memory stores a node value. A node processor performs a node processing operation using information stored in at least one of the node memory and the edge memory, stores a check node value generated by performing the node processing operation in the node memory, and stores a message generated by performing the node processing operation in the edge memory. A switch switches outputs of the node memory and the node processor through a permutation operation. A parity check verifier parity-checks an output from the node memory. A controller provides a control signal for controlling the node processor.

    Abstract: An apparatus and method for scaling an LLR for an error correction code in a mobile communication system are provided. In the LLR scaling apparatus, an environment factor controller decides an environment factor according to a radio channel environment.

    Abstract: Disclosed are an apparatus and a method for iterative decoding of a plurality of Frame Error Check (FEC) blocks included in a frame in a wireless communication system. The method includes decoding a first FEC block by considering a first decoding iteration count; determining whether there is another FEC block to be decoded; newly setting a second decoding iteration count for a second FEC block when there is the second FEC block, in such a manner that a number of times of the iterative decoding is actually used for decoding the first FEC block is subtracted from the first decoding iteration count, and the obtained difference value is added to the second decoding iteration count, which has been set for the second FEC block; and decoding the second FEC block by considering the newly set second decoding iteration count.
