Abstract :
Erasure decoding methods for an LDPC-coded FH-OFDMA system to combat the intercell interference in downlink cellular environments are proposed. With the proposed methods using simple erasure detection schemes, the performance is remarkably improved in partially interfered cases with only negligible performance loss in uniformly interfered cases.
