Among these, the most important issues are: the world's authorized UWB regulations, the designing of low-price and low-power UWB CMOS chip that can be large-scale manufactured, a new UWB system structure which can coexist with narrowband communication systems and maximize its own capacity. 这其中包括:世界范围内UWB规程的批准;能够大规模生产的低价位低功耗UWB芯片的设计:既能与现有窄带通信系统和平共处,也能避免多用户干扰。
Managers and staff on management and evaluation capacity of divergence, managers has better self-evaluation, while the technical type of staff is not authorized its management capacity assessment. 而且员工对管理者的管理水平和能力的评价分歧较大,管理工作人员的自我评价较好,而技术类员工并不认可其管理能力的评价。
Two sets of signals respectively modulated on the amplitude and phase quadratures of the signal beam by the sender are simultaneously extracted by the authorized receiver with the scheme of the dense-coding correlation measurement for continuous quantum variables, thus the channel capacity is significantly improved. 信息发送者同时将振幅和位相信号调制到信号光场上,然后将其返回到接收者处,接收者利用连续变量量子密集编码关联测量解调信号,因此信道容量被大大的提高。
