چکیده

Hybrid automatic repeat request (Hybrid ARQ or HARQ), an extension of ARQ that incorporates forward error correction coding (FEC), is a retransmission scheme with errorcontrol method employed in current communications systems. In standard ARQ, redundant bits are added to data to be transmitted using an error-detecting code, e.g., cyclic redundancy check (CRC). The contribution of HARQ is its efficient utilization of the available resources and the provision of reliable services in latest-generation systems.

Incremental Redundancy Hybrid-ARQ with Rate Compatible LDPC Codes

Hybrid ARQ (HARQ) is well known link adaptation scheme which improves system throughput combining the error correcting codes and retransmission scheme. The incremental redundancy (IR) HARQ transmits parity bits incrementally when the retransmission is requested and normally provides higher throughput than the Chase combining by adaptive transmission in accordance with channel variations. In thi...

Hybrid ARQ Scheme with Antenna Permutation for MIMO Systems in Slow Fading Channels

In this paper, an equivalent model for the hybrid automatic retransmission request (HARQ) multi-input multi-output (MIMO) systems with a proper combining scheme is first introduced. Based on this effective model, we present a simple technique, termed antenna permutation scheme (APS), which permutates the transmit antennas at each retransmission to improve the diversity gain from retransmissions...
