cochannel interference meaning in Chinese
同信道干扰
Examples
- 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。 - The underwater acoustic channel is very complex where cochannel interference , doppler frequency offsets , narrow bandwidth and time and frequency selective deep fades obstructs the development of high speed and fidelity underwater data transmissions . thus projects of high speed and fidelity underwater signal transmissions become a hotspot in the fields of world academic circles . the conventional serial communication must use adaptive equalizer to combat the multipath in real - time
海洋水声信道是一种极其复杂多变的时-空-频变参信道，其信道窄，强多途干扰，信号起伏衰落严重，一直是水下信息可靠高速传输的主要障碍，因此如何在水声信道中高速率准确地传输数据，就成为世界性的热门课题。 - Smart antenna may reduce coggege of electronic engineering of uestc , the cochannel interferences ( cci ) , enhance the user capacity and spectrum efficiency , reduces the transmit power and electromagnetic interferences , enhance the transmit efficiency , dynamically divide cells in third generation cellular
智能天线技术应用于第三代移动通信系统中具有可以减小因频率复用造成的共信道干扰( cci ) 、提高频谱利用效率及增大系统容量、减小发射功率和空间电磁干扰、增加发射效率、对小区进行动态划分等优点。 - More efforts are focused on analysis and computer simulation of the cochannel interference and ieee802 . 11b interference ' s impact on bluetooth performance respectively in awgn and rician fading channel . furthermore , the scheme of designing bluetooth point - to - point experimental system with the rok101 007 module and free bluetooth protocol stack cstack is discussed . results in this thesis provide valuable references for the deployment of bluetooth networks
然后，通过建立模型，本文在理论上详细分析了awgn信道和rician衰落信道中蓝牙同信道干扰，邻信道干扰以及同频段ieee802 . 11b干扰对蓝牙ber性能，数据以及语音链路性能的影响，并针对各种情况分别进行了详细的计算机仿真，其结果对蓝牙网络的铺设具有一定的指导意义。
