摘　　要：在LTE网络建设过程中,遇到一些挑战。LTE采用的频段较高,比CDMA路径损耗和穿透损耗高,LTE的覆盖能力弱于CDMA。本文分析了LTE系统与CDMA系统不同的链路损耗,并选取不同的典型场景进行测试验证,得到LTE系统功率需求比CDMA大12d B的结论,并且提出了LTE系统与CDMA系统的N:1合路解决方案,实现了LTE与CDMA系统的同步覆盖。In the LTE network construction process, some of the following challengesare encountered. The frequency band of LTE is higher than that of CDMA, and the LTE coverage is less than CDMA. This paper analyzes the different link loss in LTE system and CDMA systemwhichisverified by different typical scenarios.Conclusion can be made that LTE system power requirements greater than CDMA 12 d B.The N：1 combiner solutions is put forward to achieve synchronization coverage of LTE system and CDMA system.
