21885 仿真验证了新算法的特性，并与其他的算法进行了比较分析。 It is confirmed that the proposed scheme is capable of acquiring BOC (m,n) signals. It is especially compared with the traditional BPSK-like method and the results show that the SSCF scheme performs much better in the acquisition success rate and peak-to–average ratio despite the noise interference.
21886 该文通过对经典低旁瓣 MIMO 雷达发射波形设计方法的改进，提出一种新型的低旁瓣 MIMO 雷达发射波形设计方法。 A novel low sidelobe method is proposed through the improvement of the classical method of MIMO radar transmit waveform design.
21887 该方法首先引入发射波形主瓣下界、主瓣上界两个参数，并设定主瓣下界的值； Firstly, two parameters, involving the lower boundary and the upper boundary of the mainlobe of the transmitted waveform, are introduced. While the value of the lower boundary is given.
21888 其次分别以最小化峰值旁瓣、最小化积分旁瓣为目标函数，以发射信号协方差矩阵半正定、各阵元发射信号恒功率为约束条件，在此基础上，在约束条件中加入对主瓣波动的限制，建立半正定规划优化问题，并且可通过设定不同的主瓣上界的值来控制主瓣波动、抑制旁瓣； Secondly, a semidefinite programing optimization problem is established, whose objective function is minimization of peak-sidelobe or integrated-sideloble. The transmit waveform covariance is semi-positive and the signal power of each array element is fixed. Further, the restriction on the mainlobe fluctuation is added to the constraint of the optimization problem. What's more, if the upper boundary is changed, the mainlobe fluctuation and sidelobe will be changed simultaneously.
21889 最后利用一次凸优化算法得到全局最优解。 Finally, only once convex optimization algorithm is used to obtain the global optimal solution.
21890 仿真结果表明，该方法在只需求解一次凸优化问题的前提下，所设计波形旁瓣降低且可控。 Simulation  results  indicate  that  cognitive  LEO  satellite  is  able  to  select  optimized  spectrum  sensing strategy dynamically according to the idle states of primary channels with the interference limitation of primary user, and access primary channels more positively especially when the signal-to-noise ratio of detecting signals is low. The  influence  of  spectrum  sensing  uncertainty  on  the  efficiency  of  channel  access  is  depressed  and  the throughput of cognitive system is improved by the proposed channel access strategy.
21891 由于移动设备处理能力和能量的限制，近年来提出了一种新型移动云环境，通过 Ad-hoc 方式共享邻近设备的闲置资源完成数据处理、存储等需求。 In order to solve the limitation of processing capacity and energy of single mobile equipment, the conception of Ad-hoc mobile cloud is proposed recently, in which a mobile device can use the idle resources at other neighboring devices for processing data and storage in Ad-hoc manner.
21892 在此背景下，该文提出一个在源设备与邻近设备之间的任务卸载方案。 To this end, this paper designs a workload distribution for offloading among mobile equipment.
21893 考虑无线网络环境下移动设备的移动性导致连接时间随机性问题，采用随机规划方法补偿连接时间预测不精确对任务卸载带来的不利影响。 Considering the random and intermittent connections between mobile equipment caused by the movement in wireless network, a stochastic programming method is adopted to take posterior recourse actions to compensate for inaccurate predictions.
21894 同时，为了激励移动设备相互协作、最大化各自收益，提出基于买卖博弈的分布式多阶段随机买卖博弈任务卸载(SGWD)算法。 Moreover, in order to motivate the available mobile equipment for offloading while maximizing their utilities, a distributed multi-stage Stochastic buyer/seller Game for Workload Distribution (SGWD) is formulated.
