| 摘 要： | 基于TD-SCDMA系统,提出了一种在高速下行分组接入(HSDPA)中将追踪合并算法应用于混合自动重传请求技术的方案,并给出追踪合并HARQ算法,用吞吐量和误块率2个性能指标来衡量该算法的优劣,然后对不同信道条件和参数下的下行链路性能进行了仿真。结果表明,该方案对于提高下行链路的吞吐量和降低误块率具有较好的效果。

| Abstract: | The HARQ scheme,in which chase combining algorithm is applied,is proposed based on TD-SCDMA system,and tracking merger HARQ algorithm is given.Two performance indicators,which are throughput and false piece rate,are used to measure the advantage and disadvantage of the algorithm.The downlink performance under some conditions such as different channel environment or different control parameters is simulated.Simulation results exhibit the effectiveness of the chase combining HARQ scheme in reducing block erro... |
