FDD-LTE Chamber Depth Of Coverage And Network Optimiaztion Method Reaearch

Compared with traditional 2g/3 g network, the 4g network signal transmission problems such as loss of fast fading, space, through outdoor base station indoor coverage is very difficult to achieve, this makes the 4g era interior more obvious weak coverage problem. Points at present, the telecommunication operators, design institute, room equipment manufacturer only traditional GSM/WCDMA room planning and optimization experience and case, no complete FDD-LTE room planning optimization scheme, this paper aims to solve the problem.This paper systematically studied the FDD-LTE depth coverage planning process and the optimization method. Paper main work is as follows:1. This paper introduces the FDD-LTE physical resources with the frame structure, the OFDM technology, multiple antenna, to represent the future development trend of the 4g network at the same time the multicarrier polymerization is analyzed.2. Summarizes the FDD-LTE subsystem of the composition and construction components room selection principles, combined with the technical features of the 4g network chamber subsystem planning process are summarized.3. Summarize the FDD-LTE room network construction principle and construction scheme. Room points the direction for the future of network is studied in the indoor the principle of small stations.4. Summarizes the FDD-LTE coexist with other system problem, this paper introduces the principle of all kinds of interference, through detailed stray interference and the calculation of barrage jamming, the FDD-LTE is obtained and isolation requirements of each system provides data support for the project to avoid interference.5. Summarizes the FDD-LTE network optimization content and process, and puts forward the points network optimization process and matters needing attention, the detailed content of optimization to specific optimization scheme is proposed.
