多天线系统 meaning in English
multiaerial system
Examples
- The essence is users in a group shares their antennas and resource through distributed process and transmition to form a “ virtual array ”
其原理是各用户通过分布式传输和处理,分享他们的天线和其它资源从而形成一个多天线系统。 - Evolving the underlying networks to support a mass market , however , presents a number of challenges : spectrum is a limited resource ; cdma standards have sub - optimal spectral efficiency ; layered 3g network architectures are not conducive to low - latency services ; and capacity - enhancing smart antenna or multiple antenna systems have been disappointing
但开发基本网络以满足广大市场，仍面临几大挑战：频谱资源有限、 cdma标准的光谱效率未达最优、分层3g网络架构未能实现即时服务、及容量增大的智能天线或多天线系统仍不尽人意。 - Moment method is used for the analysis of interference among the vehicular multiple antennae in this paper . the multiple antennae system is equivalent to a microwave network , then the admittance matrix of the network can be obtained . using the admittance matrix , we can analyze the characteristic of coupling between two antennae and the near field of the antennae by the mom
本文采用矩量法对车载多天线间的相互干扰特性进行了分析，将多天线系统等效为微波网络，然后采用矩量法求该网络的导纳矩阵y ，利用该导纳矩阵对天线间互耦特性进行分析，同时计算天线的近场分布。 - Delivering quality video over wireless channels in real time is a challenging task . this isprimarily because of the throughput of a wireless channel may be reduced due to multipath fading , cochannel interference , and noise disturbance . therefore , there is a critical need forrobust transmission of video over wireless channels . recently , the emergence of mimo - ofdm has stimulated great interest in real time video communication , because this system can offer broadband for the multimedia data transmission over wireless channels
因为传统的视频压缩技术是针对单天线系统,只产生单一的比特流,这与多天线系统不相适应,为此,需要将视频信号分解成相应的多个码流。本文探讨一种将能视频信号分解成多个码流的多描述编码方法,以适应多天线系统的传输。 - Firstly , the effects of short - delay multipath to the dll , pll , and snr of receive signal are discussed . then the effects of multipath to multiple closely spaced antennas are presented . and solve the problem by promote a new method based on extended kalman filtering , which utilize the correlation of measure data of dll , pll and snr of each antenna
最后，利用小范围多天线系统中多径信号对接收机码环、载波环及信噪比影响的相关性，提出了基于扩展卡尔曼滤波器的多径干扰抑制技术，解决了近距多径信号的抑制问题。
