1) signal space diversity
信号空间分集
1.
In single antenna systems, signal space diversity (SSD) has been introduced as an alternative scheme to achieve an additional diversity gain.
在单天线系统中,信号空间分集(signal space diversity,SSD)是一种可供选择的方案,它可以提供分集增益。
2.
In this paper,a new DF cooperative scheme based on signal-space diversity is propesed,in which the retransmission signals of each user always contain its own data frame and are designed in signal space diversity(SSD) manner.
该文提出了一种基于信号空间分集的解码前传协同方法,该方法的协同用户重传信号中包含自己的数据帧,并以信号空间分集的方法设计重传信号,这样既能够减小用户间信道的不对称性带来的影响,又提供了一种更为高效的信号分集方式。
2) SSD
信号空间分集
1.
Different from time diversity,frequency diversity and spatial diversity which have been extensively studied,Signal space diversity (signal space diversity, SSD) is a power and bandwidth efficient diversity technique that does\'t need additional resources.
与已经广泛研究的时间、频率和空间分集不同,信号空间分集(signal space diversity,SSD)是一种功率和带宽有效的分集技术,不需要额外的资源。
3) spatially distributed signal
空间分布信号
1.
Based on wavelet transform of spatially distributed signal,a new damage detection method is put forward.
以空间分布信号的小波变换技术为基础,提出了一个识别岩石材料损伤的新方法。
4) Spatial signal separation
空间信号分离
1.
Spatial signal separation can be realized by adaptive beamforming technique.
自适应波束形成可以实现空间信号分离。
5) Signal sub_space decomposition
信号子空间分解
6) space signal
空间信号
1.
The space signals of GPS and Galileo were introduced and analysed.
介绍和详细分析了GPS和Galileo的空间信号。
补充资料：信号
信号
signal
信息的传递需要有适当的物质载体，并需要变换成某种表现形式，信息的物质载体和表现形式称为信号。系统的输入和输出即是信号，故应称输入信号和输出信号。输入信号通过系统被变换成相应的输出信号。
