| 1. | A is the nominal output of the auxiliary signal .
A是附加信号的额定输出。 |
| 2. | A is the nominal output of the auxiliary signal
A是附加信号的额定输出。 |
| 3. | The auxiliary signal is near by the base - station in the second calibration project for mutual coupling existing between sensors and channels and sensors uncertainty
两种方案均是在用辅助信号的扩频码对其进行解扩基础上进行的。 |
| 4. | Based on plenty of existing research findings at home and abroad , this thesis studies several online calibration algorithms with an auxiliary signal source for the wcdma - based adaptive antenna array according to their practical application
本论文在国内外现有工作基础上，根据工程实际，综合研究了wcdma系统的天线阵列有源校正算法。 |
| 5. | The auxiliary signal is injected into antennas from the ports of antennas in the first calibration project for channels uncertainty . this thesis studies the least squares ( ls ) algorithm , the subspace - based algorithm and the correlation algorithm based on the mentioned project
通过理论研究，确定基于有源方式的两种天q线阵列校正方案：一种是从天线馈电口注入辅助信号，另一种是从空中注入辅助信号。 |
| 6. | The two calibration projects are both based on de - spreading the reference signal . because they require a prior knowledge of the auxiliary signal , such as pn spread code , doa , constant modulus and so on , the fast and robust convergence can be ensured , and the multiple - access interference ( mai ) can be eliminated
由于利用了辅助信号源的先验知识，如扩频码、辅助信号的doa 、比特信息及恒模特性等，有源校正技术不仅克服了自校正技术收敛慢的弱点，还消除了不利于校正的多径影响。 |
