Abstract

Abstract:

With the development of coastal fisheries and marine tourism,the demand for wireless coverage on offshore is becoming more and more urgent.Based on the analysis on the characteristics of the mobile communication business,the difficulties of offshore coverage planning,coverage optimization techniques for the actual application scenarios of coastal areas,a TD-LTE network coverage optimization method which made comprehensive use of the following technologies including special TD-LTE system parameter configuration,optimization of wireless communication link budget,optimization of the base station site planning and coverage enhancement technologies was proposed.The proposed optimization method was practically implemented in the Shangchuan Island and Xiachuan Island.The simulation results and measured data in the project field show that the implementation of TD-LTE network coverage optimization method has obviously improved the network coverage rate and communication service quality.

Key words: wireless coverage on offshore, TD-LTE, link budget, coverage enhancement

Interference analysis of TD-LTE downlink signal on S-band pulse radar fuse Abstract:Concerning that the TD-LTE downlink signal and pulse radar fuze signal may be interfered within 2 300 to 2 400 MHz band of S-band,the method of calculating the signal-to-interference ratio at the pulse radar fuse receiver was used.And the isolation distance that the TD-LTE downlink signal did not interfere the pulse radar fuze signal under the condition of other factors determined was obtained.The validity of the conclusion through the link level simulation was verified.At the same time,it was also obtained when the horizontal distance between the two was isolated distance,the transmission power of the base station was increased (or the fuze transmission power was reduced),the ground effective reflection area was reduced,the fuse will also be interfered by TD-LTE downlink signal.
