upstream channel

The investigation of the upstream-downstream intermittent reversing flow in the near wall of a 2-D channel is attempted with a 2-D laser doppler velocimeter ( LDV).

本文应用二维激光多普勒测速仪（LDV），对二元通道内近壁间歇性反流特征做了尝试性测量。

Design of DBA Algorithm in EPON Upstream Channel in Support of QoS

支持QoS的EPON上行动态带宽分配算法设计

This system is not only technically easy to achieve, but also made full use of the idle users upstream channel to completely solve the backbone network and server load overload problems.

这个系统不仅在技术上容易实现，而且充分利用了用户空闲的上行信道，从而彻底解决对骨干网以及服务器的负载过载的难题。

Research of Upstream Channel Bandwidth Allocation Algorithm In HFC Network

HFC网络中上行带宽分配算法的研究

Ingress noise has great proportion in sorts of noise on upstream channel in HFC.

在HFC网络回传通路各类噪声中，输入噪声占有相当大的比重。

Upstream channel noise consist of input noise in about 70%. Abstract the input noise in a model of narrow band interference and take a nonlinear suppression measure. Construct a nonlinear narrow band interference suppresser and simulate in the SCDMA system.

在HFC网络回传通路中有近70%的噪声是输入噪声，把输入噪声抽象为一个窄带干扰模型，对其采取非线性抑制措施，构造了一个非线性窄带干扰抑制器，在SCDMA系统下做了仿真；
