<p>允许控制和资源分配问题可以追溯到90年代。在[<一个href="#B4">4</一个>,<gydF4y2Ba一个href="#B5">5</一个>],Fo年代ch我n我和Miljanic提出了一个分布式异步功率控制算法在传统的蜂窝系统预定义signal-to-interference-plus-noise约束下,该收敛于最优功率分配方案,最大限度地减少总传输功率。此外,分布式功率控制问题在特定于用户signal-to-interference-plus-noise比(SINR)和功率预算约束被认为是在<一个href="#B6">6</一个>),分布式约束功率控制(DCPC)和异步分布式约束功率控制(ADCPC)计划开发最大化最小SINR同步和异步更新,下的所有用户。在[<一个href="#B7">7</一个>,<gydF4y2Ba一个href="#B8">8</一个>),允许控制问题进行了研究,以及大量的单个或多个发射机去除算法报告。其中,逐步最大干扰消除算法(SMIRA)是最有效的一个最小的故障概率。最近,有趣的研究工作录取和功率控制的框架下认知目前网络报道(<一个href="#B9">9</一个>-

SMIRA (I-SMIRA)提出了最大化承认SUs的数量。在所有上述认知目前网络文学,没有对代码进行优化渠道(签名)的二级用户。相比之下,代码设计为二级链接目前被认为是在<一个href="#B12">12</一个>- - - - -

<p>我们最好的知识,介绍了第一个研究工作的问题与主建立二级目前链接共存窄带系统。因为二级用户的宽带传输通常经验多路径衰落,耙匹配滤波器是利用二次接收器(SRs)。我们的目标是最大化承认二级链接的数量和活跃的二级链接下的总能耗最小化以下约束:(1)在中学RAKE接收机的SINR约束,(2)干扰约束在主接收器(PRs),和(3)传动功率峰值约束二次发射机(STs)。这个优化问题是一个np难问题,激励的发展有效的次优算法,提供良好的解决方案。我们提出一个迭代算法来解决这一问题的产生一个次优的解决方案认知网络性能特征的承认SUs的数量和网络能耗。我们提供数值结果表明我们的算法优于现有的签名设计和允许控制算法之前提出的文献。</gydF4y2Bap>

<p>在这里,我们考虑联合承认SUs的数量最大化和最小化二次能源消费总量的认知无线电网络(CRN)。目标是找到一个联合接纳控制和资源(即。,power and signature) allocation scheme that maximizes the number of SUs accessing the spectrum and minimizes the total energy consumption. Minimizing total network energy is an important problem especially when the network has a constraint on the interference it can cause to other neighboring networks. Since our goal is to admit as many users as possible and minimize the energy consumption of the network, we initially formulate the problem as a multiobjective optimization problem with three sets of constraints: (1) SINR constraints at the SRs, (2) interference temperature constraints at PRs, and (3) power budget constraints at the STs. We can now formulate problem, referred to as P, as follows:<年代pan class="equation" id="EEq8"> <svg height="197.27499" id="M46" preserveaspectratio="xMaxYMin"
