This paper has presented a new constellation rearrangement (CoRe) theme for a good performance/complexity tradeoff if circular buffer rate matching (CBRM) is applied for incremental Hybrid ARQ (IR-HARQ) with turbo coding or LDPC coding. The presented technique is applied to high order modulation, such as 16QAM and 64QAM, with 2 versions. For all transmissions of one HARQ process, the previous half...
Channel coding for IMT-ADVANCED system needs to support higher data throughput and transmission rate. Due to the inherent encoder/decoder parallel feature, low density parity check (LDPC) codes is more suitable for hardware implementation than turbo codes when the data throughput is higher than 100 Mbps. As one of the contributors to Wimax LDPC and 3GPP2 LDPC, ZTE has funded some experience in the...
