Apparatus and method to transmit/receive signal in a communication system |
摘要 |
An apparatus and method for transmitting/receiving a signal in a communication system are provided. A signal reception apparatus of a communication system receives a signal and generates a child Low Density Parity Check (LDPC) codeword vector by decoding the received signal according to a child parity check matrix supporting a first coding rate. The child LDPC codeword vector includes an information vector including A (A≧1) information bits, and when the first coding rate is equal to a coding rate for a case where D (D≧1) parity bits are punctured among B (B≧1)+C (C≧1) parity bits included in a parent LDPC codeword vector generated by encoding the information vector according to a parent parity check matrix supporting a second coding rate, a child bipartite graph corresponding to the child parity check matrix is generated such that a parent bipartite graph corresponding to the parent parity check matrix corresponds to an edge merge scheme. |
