摘要本文基于码率匹配截短Turbo码和“码字校验交替重传”方案,提出了一种新的Ⅱ型混合ARQ方法,并将其应用于移动通信系统的分组数据业务中。仿真结果和分析表明,综合系统性能和复杂性两方面考虑,该方法不失为一种实现分组数据可靠传输的最佳解决方案。 In this paper, a new type-Ⅱ Hybrid ARQ scheme based on RCPT codes and 揳lternate codeword retransmission and parity retransmission?(CPC) strategy is introduced to error control mechanism in data communications. Simulation results show that the proposed scheme is an optimum solution to realize a reliable data transmission for both performances and complexity consideration.
