Engineering and Implementation of Digital TV Platform & Wireless Coverage System;

This paper studies the TD-SCDMA wireless coverage in the high-rise residential communities and puts forward the corresponding solutions.

in light of characteristics of cell CDMA network, this paper analyzes relevant factors influencing wireless cover, including its changes both with and unloaded; impact from neighboring housing estate on the cover property; influence on the cover property of network loaded after introducing MUD, as well as influence on wireless cover from difference information bit rate.

The influences of structure parameters such as thickness,average float,and cover factor on the heat transfer of the fabric were investigated.

The factors to influence size shedding,such as size soakage and coverage,cover factor,yarn surface hairiness and size composition,are analysed and compared.

The function of preventing stop mark key on air jet loom was flexibly applied to solve weft bar defects such as thin bar,thick bar and shrinked end effectively,and the applicable limits of cover factor were analyzed.
