IR-HARQ scheme on Bit-Interleaved Coded Modulation

This paper proposes an error control mechanism for data transmission defined as simple Hybrid Automatic Repeat-reQuest (ARQ) utilizing Bit-Interleaved Coded Modulation (BICM). The study investigates the Bit Error Rate (BER) performance of wireless communications using high rate Hybrid ARQ enabled by the proposed Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) option. The Incremental Redundancy Hybrid ARQ (IR-HARQ) technique generates the same frame during retransmission and the frame is discarded with limited retransmissions. This study investigates the BER performance of different techniques which are combination of BICM-HARQ without iterative decoding, the independent BICM and BICM-ID in half rate recursive systematic code. The system with HARQ scheme shows good improvement compared to independent case.
