  • Partial retransmission hybrid automatic repeat request (ARQ) scheme is presented based on soft bit value. In this scheme, bits of lower soft bit value is first transmitted in retransmission, because they are the main reason generating wrong data packet. The average bit soft value of new scheme is researched and the formula of BER in the additional white Gaussian noise (AWGN) channel is derived. Theoretic analysis and numerical results indicate that soft bit value-part repeat-hybrid automatic repeat request (SBV-PR-HARQ) could average the bit soft value and make the system have better performance.

Abstract: Partial retransmission hybrid automatic repeat request (ARQ) scheme is presented based on soft bit value. In this scheme, bits of lower soft bit value is first transmitted in retransmission, because they are the main reason generating wrong data packet. The average bit soft value of new scheme is researched and the formula of BER in the additional white Gaussian noise (AWGN) channel is derived. Theoretic analysis and numerical results indicate that soft bit value-part repeat-hybrid automatic repeat request (SBV-PR-HARQ) could average the bit soft value and make the system have better performance.
