| 摘 要： | 针对比特软值较小的比特是重传时造成数据包出错的主要原因,提出了基于比特软值的部分重传混合ARQ方案,在重传时首先传输比特软值较小的比特;研究了该方案在重传之后各个比特的平均软值,并推导了在高斯白信道下重传前后不同比特的误比特率。理论分析和数值仿真表明,该方案在部分重传的情况下也能较好地平均各个比特之间的软值,从而提高了系统的吞吐性能。

| 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-... |
