简介：这篇文章分析在三节点的继电器网络中继计划，选择中继计划和增长中继计划修理的精力效率表演。靠近形式的asymptotic精力每好小点(EPG)为在高signal-to-noise的最先进的中继协议的表情比率(SNR)政体被导出。在精力消费模型，传播，电路和重发的明确的表达，精力都被考虑。为了便于在不同中继之间的精力效率表演的比较，协议，连接可靠性和重发可能性被asymptotic停止可能性在使假设褪色的瑞利下面在高SNR政体决定。计算机模拟在对称、不对称的继电器网络被执行。模拟结果显示出在这些最先进的中继协议之间的系统精力开销的差别。最后，一些实际含意能由观察制造。

简介：直角的频率部门multiplexing(OFDM)为它高速度传播的能力正在吸引更多的注意。然而，OFDM在它山峰力量的高比率拥有明显的缺乏到平均力量(PAPR)，它成为了保持它回到的主要问题被用于宽带卫星通讯系统。OFDM与时间部门multiplexing(TDM)结合了，及时划分进一些块的OFDM的副载波调子，能减少OFDM的高PAPR。同时，OFDM的优点能被保存。在这份报纸，OFDM/TDM被用于宽带卫星通讯系统。这份报纸理论上在PAPR上分析OFDM/TDM系统模型以及它的制止的效果，并且建议频率领域复合飞行员(频分多路复用飞行员)隧道评价算法。在宽带卫星通讯系统的模拟结果表演OFDM/TDM让同意性能并且减少PAPR。

简介：推进的长期的进化(LTE进展)在比得上国际活动电信的要求或优异的高系统性能的标准目标进展了(IMT进展)。以便与LTE支持向后的相容性，大多数关键技术在LTE进展，其一是不连续的接收机制(DRX)被保留了。LTE进展采用搬运人聚集技术扩大系统带宽，它要求LTEDRX在与多重部件搬运人一起要使适应多收发器情形的单个收发器的情形适用。显然，搬运人聚集将严重地影响DRX的表演因此它值得学习LTEDRX和搬运人聚集的共存在系统表演上带的影响，例如，系统延期。在这份报纸，在搬运人聚集情形的DRX的第一一概述被给。然后，它基于排队理论作为一个Markov过程被建模。模拟结果证明有一个一致迟钝定时器的独立部件搬运人配置与另外的引用计划相比完成优异服务延期表演。
