查询词典 dispreading

Totally different from the traditional algorithms for CDMA smart antennas, the new algorithm exploited the spreading codes directly within the iterative weight updating procedure instead of indirectly through the dispreading procedure.

与CDMA移动通信系统中的传统算法完全不同，新波束控制算法直接在权重迭代过程中利用了扩频码，而不是间接地通过解扩频等环节使用扩频码。

The communication technology used in GPS is a direct sequence spread spectrum structure. Using C/A Gold codes, it can cope with wideband noise (such as thermal noise and channel noise) or low power narrowband interference by its processing gain. But DS-SS can not reject high power narrowband interference completely. So we need an anti-jamming filter to reject the narrowband interference by using adaptive filters prior to dispreading.

它是利用直接展频的一种架构，因此，此系统能藉由C/A码的展频处理增益，来对付ㄧ些宽频的干扰或是低能量的窄频干扰，但是它无法应付高能量的窄频干扰，因此我们需要一个抗干扰滤波器在解展频之前来先将干扰去除。

The transmitter takes advantage of the eigenvectors of the SCM of the correlated channels to spread and weigh the signals of each layer. The spatial eigenbeams are formed to carry the signals being spread. The receiver distinguishes the signals from different beams via dispreading operations; therefore co-channel interferences are eliminated effectively.

发射机利用信道空域协方差矩阵的特征矢量，对每一层发射码元进行扩频和特征波束形成加权，形成正交的空域特征波束来承载扩频后的信号码元；接收机则通过解扩处理分离来自不同波束上的信号，有效地抑制了共信道干扰。

In order to disclose the adaptive strategies and capacity of Potaninia mongolica Maxim, acquired during its evolution history, the whole response system, which was composed of individual morphology plasticity response, organs anatomy structure response, physiological function response of anti-arid and anti-hotness, activities of protective enzymes response, endogenous hormone adjustment response, sexual reproduction strategies response of seeding, dispreading, sprouting and renewing, asexual reproduction strategies response of clonal growth patterns, clonal growth architectures, clonal growth architectures plasticity, heterogeneous resources utilization strategies, endogenous hormone distribution in clonal organs, foraging behavior, risk-spreading, and resource sharing, individual density allocation patterns response, niche differentiation response, species connection response, allelopathy response and biodiversity components response of the plant was profoundly explored in this paper.The studies come to at least four important results:(1) Taking the sensitive response and evading strategy to adapt to environment stress, Potaninia mongolica Maxim is a successful species has lived through the long-term evolution. Nevertheless, it is narrow climate and soil niche and characteristic of vegetation reproduction which has made the plant a rare and endangered species.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
