Selective Retransmission Method for HARQ
IEICE Transactions on Communications, 2011 A new selective retransmission method for HARQ (Hybrid Automatic Repeat reQuest) systems is proposed. This method can avoid the blindness of symbols retransmission by the transformation of lostmap matrix and simulation results show that the proposed method can reduce the number of retransmissions effectively.

HARQ-Chaotic: Analog Chaotic Code Applied in HARQ Scheme of Wireless Communication System [PDF]
Wireless Communications and Mobile Computing, 2019 This paper proposes a novel symbol-level combining hybrid automatic repeat request (HARQ) scheme based on analog chaotic code and named HARQ-Chaotic. The transmitter of HARQ-Chaotic adopts analog chaotic code to encode Quadrature Amplitude Modulation (QAM) symbols of retransmission packets to combat fading and noise. As the analog chaotic code can only
