    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: The present invention relates to an accounting method and an accounting apparatus in a mobile communication system. The amount of radio resources and traffic used by a mobile terminal of each subscriber accessing a base station can be measured and analyzed without changing a structure of the mobile communication system. In addition, since a provider who does not own an IP network and thus uses a leased network of an existing provider can measure and analyze the amount of traffic used by a mobile terminal in the leased network regardless of an IP network of the existing provider, a more precise accounting reference can be provided to the corresponding provider.

    Abstract: An apparatus and method for generating LLRs in an MIMO communication system. In a receiver for a spatial multiplexing communication system, a determiner performs an MML decoding operation in an ascending or descending order of TX antennas to estimate a plurality of candidate TX vectors. A distance calculator calculates a Euclidean distance for each of the candidate TX vectors from the determiner. An LLR calculator calculates LLRs using the Euclidean distances from the distance calculator. Accordingly, it is possible to generate an LLR with high reliability at low complexity in an MIMO communication system.

    Abstract: An apparatus and method is provided for increasing a channel change speed in a Digital Multimedia Broadcasting (DMB) receiving terminal. The apparatus includes a DMB buffering unit for buffering DMB data, a DMB extractor for extracting only DMB data of a currently set channel, and a controller for setting a changed channel into a DMB signal-receiving unit so that a DMB program can be output using extracted DMB data. DMB data output from the DMB signal-receiving unit is stored in the DMB buffering unit, and DMB data according to a channel set by the user is extracted. Thus, a channel change can be performed without stopping or restarting a DMB receiving operation of the DMB receiving unit, and the time required for the channel change is reduced.
