23735 该文针对 EPON 和 WLAN 构成的 FiWi 网络提出一种分级 DBA 机制。 This paper proposes an upstream fair hierarchical DBA scheme for EPON-WLAN networks.
23736 引入剩余带宽比例因子解决多个轮询周期内各用户分配的带宽资源与其权值不匹配而产生的不公平问题； Excess bandwidth proportion factor is introduced to address the unfair issue due to the unmatched problem between the allocated bandwidth resource and the assigned user weight among multiple granting cycles.
23737 联合考虑业务优先级、带宽请求比例和网络负载解决带宽分配中的业务 QoS 保证和信道带宽浪费问题。 On the other hand, in order to deal with the QoS guarantee and bandwidth waste issue in bandwidth allocation, we jointly taken into account of different traffic QoS priorities, bandwidth requirement proportion, and actual traffic load.
23738 仿真实验表明，与现有文献的 DBA 机制相比，系统公平性、吞吐量和信道利用率有明显提升。 Extensive simulation results show that compared with the existing DBA schemes, the proposed hierarchical DBA scheme can improve proportional fairness, throughput and channel utilization.
23739 且所提 DBA 算法不限定具体带宽资源类型，具有良好通用性。 Moreover, the proposed FiWi DBA scheme does not refer to a specific bandwidth resource types, thus obtains good generality.
23740 由于 LCLC 谐振变换器能够同时实现开关管的零电压、零电流开通和关断，因此广泛应用于行波管电源中。 As the advantages of zero-current-switching and zero-voltage-switching, the LCLC resonant converters are widely used in power supplies of Travelling-Wave Tubes (TWT).
23741 然而，在实际电路测试中出现的“反向谐振电流”以及“开关管关断时谐振电流不为零”的问题，造成 LCLC谐振变换器的效率下降。 However, the problems such as the reverse resonant current and the non-zero resonant current in the converter drop the efficiency.
23742 该文从 LCLC 谐振变换器的工作原理出发，推导了上述两个问题出现的原因，并给出了解决方案。 In this paper, the above problems are explained by the working principle of the converter and the solutions to the problems are also given.
23743 通过软件仿真的方法，给出了用于 LCLC 谐振变换器的经验数值。 Based on the simulations, empirical data is given to guide the design of the LCLC resonant converters.
23744 最后，通过软件仿真以及实际测试两种方法验证了上述分析。 Finally, the analysis is validated by the simulations and experiments.
