Hybrid automatic repeat request (HARQ) combines ARQ and forward error correction (FEC) in order to benefit from the advantages offered by both schemes. This chapter focuses on the use of HARQ in multiple-input multiple-output (MIMO) systems, not only because single-input single-output (SISO) can be viewed as a special case of MIMO, but also because MIMO transmission is nowadays used in most commercial wireless systems, including IEEE 802.11 and 802.16. The chapter presents a physical layer model for wireless transmission using HARQ. It then addresses the design of the transmitter and receiver. The performance of different HARQ schemes is compared in terms of the implementation of the receiver, as well as the wireless channel through which transmission takes place.
