57498 仿真结果表明，在 Nakagami-m 信道衰落的无线通信环境下，采用“收集－存储－使用”能量收集方案的无线通信存在最佳时隙数，以实现最大有效的吞吐量，而采用“收集－使用”的能量收集方案时，无线通信会使用少量时隙来平衡误码率和通信迟延. The simulation results show that the wirelesscommunication adopting the “harvest-storage-use”strategy has the optimal number of time slots to a?chieve the best effective throughput，while the wireless communication adopting the “harvest-use”EHscheme should use a small number of time slots to balance the bit error rate and communication delay.
57499 提出一种简单结构的双频带带通滤波器，由不等长十字形谐振器和平行耦合线馈电结构组成. A simple dual-band band-pass filter is proposed. It is composed of an unequal-length cross- shaped resonator and parallel coupled lines feed structures.
57500 由于滤波器分布电路具有对称性，首先利用奇偶模分析法对带通滤波器奇偶模输入阻抗、传输零点和传输极点进行分析. Due to the symmetry of the filter distribution circuit，the transmission zero and transmission pole are analyzed using the even-odd mode analysis meth- od.
57501 所设计的滤波器具有 3 个传输零点和 4 个传输极点. The designed filter has 3 transmission zeros and 4 transmission poles.
57502 传输零点的位置不随阻抗参数的变化而变化. The positions of the transmis- sion zeros do not change with the changing of the impedance parameters.
57503 在 4 个传输极点中，第 1 个偶模传输极点和第 1 个奇模传输极点构成了第 1 个通带，剩下 2 个传输极点构成了第 2 个通带. Among 4 transmission poles， the first even-mode transmission pole and the first odd-mode transmission pole constitute the first pass- band，and the remaining two transmission poles constitute the second passband.
57504 与等长十字形谐振器滤波器相比，该结构多了一个极点. Compared with the e- qual-length cross-shaped filter，this structure has one extra transmission pole.
57505 滤波器的通带带宽可以通过调节传输极点位置进行调整. The passband bandwidth can be adjusted by adjusting the position of the transmission poles.
57506 给出了滤波器实物的结构参数，并且利用仿真软件进行仿真优化，得到了滤波器插入损耗和回波损耗的仿真结果. Then the physical parameters of the designed filter are given.
