简介:针对蜂窝网络下D2D通信系统提出了一种遍历容量分析方法.首先,对蜂窝网络下D2D通信模型进行了概述,并分析了其上行时隙和下行时隙的干扰情况.在D2D通信系统中很难得到瞬时的信道状态信息,故假设基站和终端仅知道统计的信道状态信息,且信道系数服从独立复高斯分布.基于上述假设,针对上行时隙得出DUE的信干噪比(SINR)表达式,并基于该公式推导出DUE的SINR的概率分布函数和概率密度函数,最终推导出DUE的上行遍历容量.利用相同方法,推导出下行遍历容量.仿真结果表明,即使存在较多DUE情况下仍然可以取得较高的遍历容量.研究结果可用于D2D通信系统的设计与优化。

简介:摘要目的探讨UNC13D及MYO5A基因突变的原发性噬血细胞综合征的发病机制。方法对2022年1月28日解放军联勤保障部队第九四〇医院收治的1例UNC13D及MYO5A基因突变的成年噬血细胞综合征患者的相关实验室检查、其近亲属的基因图谱及治疗预后进行回顾性分析,并复习相关文献。结果患者最终诊断为原发性噬血细胞综合征,经噬血淋巴组织细胞增生症(hemophagocytic lymphohistiocytosis,HLH)-2004方案化疗2次,与其胞哥HLA配型为半相合,考虑其胞哥携带噬血相关基因,不宜选做供者,无其他适合亲缘供者。遂转外院拟行异基因造血干细胞移植,电话随访未行异基因造血干细胞移植,死亡。结论原发性噬血细胞综合征基因突变为其诊断的金标准,原发性噬血细胞综合征可能存在双基因遗传模式,病毒感染造成的免疫紊乱与遗传因素等多因素的共同作用可能导致原发性噬血细胞综合征的发病。
