| Abstract: |
| Many new technologies have been applied in WiMAX and LDPC(low-density parity-check) code is one of the most important technologies.This paper introduces the LDPC code used in(IEEE802.16e) OFDMA PHY layer, describes its structure and encoding method,and analyses its error-correcting performance under AWGN and ITU-3 channels. |
| Key words: WiMAX IEEE802.16e |
