- Abstract
- The present invention provides an LDPC encoder, a channel encoder of a portable internet system including the LDPC encoder, and an encoding method thereof. The LDPC encoder according to the present invention generates a Costas array, shifts it, generates an analogous circulation parity check matrix having a repeated pattern from the shifted Costas array, and performs encoding by using the parity check matrix. With this LDPC encoder, complexity of encoding system may be reduced.
