下行信道 meaning in English
down channel
Examples
- Scan for downlink channel and establish synchronization with bs
用户端设备扫描下行信道，之后于基站建立同步。 - To meet the demand on broad band services , the methods providing dual downstream channel in one cmts were studied in this thesis
为了适应宽带化的需要，本文探讨在一台cmts中提供两个下行信道的方法。 - The downstream channel is a point - to - multipoint broadcasting channel with a wider bandwidth , while the upstream one is a multipoint - to - point share medium with a narrow bandwidth
Hfc网络下行信道采用一点对多点的广播方式，用户共享下行资源实现比较简单。上行信道是一个多点对一点的媒体共享信道。 - In the implementation , we used the multiprocessing method in qnx to analyze the general flow chart of system , and divided the realization of dual downstream channel into three modules
在具体实现上采用了qnx的多进程编程思想，对整个系统的流程进行了分析设计，将双下行信道的实现分为三个大的模块进行讨论。 - With regard to modulation , cablemodem adopts qam on downlink channels , and qpsk or the more superior s - cdma on the uplink to achieve a better suppression of noise interference
Cablemodem的下行信道采用了qam调制方式，而在上行信道上，为了更好地抑制噪声干扰，通常采用抗干扰性能较好的qpsk或者s - cdma调制技术。
