Abstract

Abstract:

Compared to traditional network，the network structure has a greater impact on the quality of TD-LTE network.If only upgrade directly in the original site based on TD-SCDMA，the original structure and quality issues would be inherited.On the basis of the problems encountered in the shared antenna collaborative optimization，a collaborative network optimization method was presented.Network problems of TD-SCDMA and TD-LTE were solved from the dimensions of network structure，coverage and interference by using project parameters，measurement report，frequency sweep test，driving test and other data.After that，by using network planning and optimization tools，collaborative optimization scheme was outputted and verified in the existing network to solve these problems.Finally，TD-SCDMA and TD-LTE collaborative optimization adjustment strategy was summed up by evaluating implementation effects.

Key words: TD-LTE, TD-SCDMA, shared antenna, network optimization, collaborative optimization

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.
