1004 针对强噪声背景下微弱信号检测问题,本文把互补集总经验模式分解(CEEMD)方法和变尺度 Duffing振子结合,提出了一种新的微弱信号检测方法。 Aiming at the weak signal detection problem under strong noise background, the weak signal detectionprinciple based on Duffing oscillator is analyzed. Combining the complementary ensemble empirical mode decomposition(CEEMD)method with the variable-scale Duffing oscillator, a new weak signal detection method is proposed.
1005 利用 CEEMD 将复杂含噪信号分解为不同的固有模态函数(IMF),通过Duffing 系统分岔图及其变化找到相轨迹变化的临界阈值,实现含噪信号的信息检测。 The complexnoisy signal is decomposed into different intrinsic mode functions(IMF)by using CEEMD. Through the Duffing system bi-furcation diagram and its changes, the critical threshold of the phase trajectory change is found, and the information detectionof the noisy signal is realized.
1006 结果表明,本文所提方法不仅可以很好地免疫噪声,而且能有效检测出信噪比低至 73dB 的多频率周期信号。 The results show that the joint detection method can not only immune noise well, but also ef-fectively detect multi-frequency periodic signals with signal-to-noise ratio as low as 73dB.

1008 本文研究由一个基站和多个分簇用户组成的无线供电混合非正交多址接入系统。 In this paper, we consider a wireless powered hybrid non-orthogonal multiple access network consisting of abase station and multiple clustered users.
1009 在该网络中,基站通过无线能量传输方式给用户供能,用户则利用收集到的能量向基站传输各自的信息。 In this network, the base station transfers energy to the users in a wireless manner, and the users utilize the harvested energy to transmit information to the base station.
1010 为降低基站的接收解码复杂度,用户采用分簇的方式进行信息传输: To simplify the complexity of the basestation's information receiver, a hybrid multiple access scheme is adopted by the users, which are partitioned into multipleclusters.
1011 簇间用户的信息传输采用时分多址方式,而簇内用户的信息传输采用非正交多址方式。 The users in the same cluster transmit in the non-orthogonal multiple access manner, while the users from differentclusters transmit in the time division multiple access manner.
1012 通过联合分配能量传输与信息传输的时间长度以及控制基站和用户的发射功率来实现网络能量效率的最大化。 To maximize the energy efficiency of the network, we jointly optimize the time length of wireless energy transfer from the base station to the users and the time length of information transmission from the users to the base station, as well as the transmit powers of the users.
