58568 当发生用户属性撤销时，只需更新用户属性撤销列表，解密时根据用户属性撤销列表控制撤销属性用户的访问，可减少密文更新和用户私钥更新的计算量，提高系统撤销用户权限的执行效率，保护用户属性的隐私信息. When the user attribute revocation occurs，it is necessary to update the user attribute revocationlist from which the user authorization can be limited. Then the workload of updating ciphertext and theuser private key is lessen to improve the execution efficiency of re-encryption and access control scheme，at the same time，the privacy information of user attributes are protected.
58569 针对相关延迟键控方案信息速率低、误码性能差的问题,设计了一种相位正交多载波降噪相关延迟键控方案。 Aiming at the problems of a low information rate and the poor bit error performance of traditional chaotic keying schemes, a Phase Quadrature Multi-Carrier Noise Reduction Correlated Delay Shift Keying (PQMC-NRCDSK) scheme is proposed.
58570 该方案使用混沌序列与其时间延迟序列的叠加作为参考信号,同时混沌序列与其时间延迟序列分别与数据信息的乘积作为信息承载信号。 In this scheme, the superposition of chaotic sequence and its time delay sequence is used as the reference signal, and the product of the chaotic sequence and its time delay sequence with data information is used as the information bearing signal.
58571 参考信号和信息承载信号使用不同频率及相位正交的载波发送,并且在发送端和接收端使用多根天线来发送和获取信号。 The reference signal and information bearing signal are transmitted by the carrier with different frequencies and quadrature phase, and multiple antennas are used to transmit and acquire signals at the sender and receiver, respectively.
58572 对该方案在多径衰落信道下的误码性能进行了详尽的研究,并进行了理论与实验验证。 The error performance of this scheme in the multi-path fading channel is studied in detail and verified by theoretical analysis and experimental verification.
58573 实验结果表明:理论分析与仿真结果相吻合。 Experimental results show that the theoretical analysis is consistent with the simulation results, and the correctness of the theoretical analysis is verified.
58574 在相同载波数下,相位正交多载波降噪相关延迟键控方案的信息速率比多载波相关延迟键控方案和相关延迟键控方案的高,且为多载波相关延迟键控方案的两倍; The information rate of the PQMC-NRCDSK scheme is higher than that of the MC-CDSK and CDSK schemes under the same carrier number, and is twice as high as that of the MC-CDSK scheme.
58575 另一方面,该方案的误码性能明显优于上述方案的。 On the other hand, the error performance of the PQMC-NRCDSK scheme is obviously better than that of the above schemes.
58576 针对社会生成对抗网络行人交互特征简单且无法充分利用行人交互信息的问题,提出一种结合社会特征和注意力机制的行人轨迹预测模型。 To address the problems that the pedestrian interaction feature of the Social GAN is simple and that it cannot make full use of the most of pedestrian interaction information, this paper proposes a pedestrian trajectory prediction model with social features and attention mechanism.
58577 采用生成对抗网络模型,其中生成器使用编码器-解码器结构,中间加入注意力模块,并且设置3种社会特征以丰富行人交互信息。 This model adapts the structure of generative adversarial networks. The generator adapts an encoder-decoder model and the attention model is put between encoder and decoder.
