Abstract
In the paper, we study the RB-HARQ and the degree reliability using IEEE802.16e LDPC codes. The retransmission bits according to soft-decision output and degree in LDPC codes. We can select the bits with small absolute value of soft-decision output and the small degree has the priority to retransmit. To improve the efficiency of retransmission based on RB-HARQ using LDPC codes.
