摘要 HARQ(混合自动重传请求)技术能够很好地补偿无线移动信道时变和多径衰落对信号传输的影响,已成为LTE(长期演进)系统中不可缺少的一项关键技术。针对TD-LTE(时分双工的LTE)系统中的上下行HARQ过程,提出了一种在DSP(数字信号处理器)中的实现方案,通过在DSP中运行,验证了该方案的有效性和可行性。 As the Hybrid Automatic Repeat Request (HARQ) technology can well compensate the effects of wireless mobile channel time-varying and multipath fading on signal transmission, it has become an indispensable key technology for Long Term Evolution (LTE) systems. For the uplink/downlink HARQ process in TD-LTE systems, this paper presents an imple- mentation scheme in Digital Signal Processing (DSP). The running results in DSP verify the effectiveness and feasibility of this scheme.
