摘要
LTE-A标准的目标之一就是为用户提供更高的数据速率,这就对移动通信的可靠性提出了更高的要求,因此引入混合自动重传请求技术(HARQ)就显得很有必要。HARQ技术能够有效降低传输的误码率,提高系统的吞吐性能,提供实时性服务;而HARQ合并算法又对HARQ系统的性能有极大的影响。主要对HARQ合并算法进行仿真分析研究,找出一种性能增益最佳的合并算法。
One of the goals of LTE-A is to provide higher data rate for the user, this puts forward higher requirements on re- liability of the mobile communication,therefore the introduction of hybrid automatic retransmissiou request（HARQ） technology is very necessary. HARQ technology can effectively reduce the error rate, improve the throughput performauce of transmission system, provid real-time services;but there is a great effect of HARQ merging algorithm for the performance of the HARQ system. This paper mainly based on the HARQ merging algorithm research and simulation analysis, finds out the merge algorithm for the best performance gain.
