A Type-II HARQ Scheme Using Interleaving Rearrangement and Constellation Rearrangement
Yan Yao · Telecommunication Engineering · 2004
Hybrid automatic repeat request (HARQ) protocol is always used for reliable high rate wireless services for the purpose of improving throughput and decoding efficiency of communication systems. This paper presents a new type-II HARQ scheme using constellation rearrangement and interleaving rearrangement. The retransmission protocol is described and then throughput is analyzed. Simulations show that the proposed scheme achieves higher throughput, reduces the transmission delay and improves the reliability of the system.
