摘要： 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.

摘要： 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.
