摘　　要：终端路测数据表明:蜂窝无线网络中存在大量的模三干扰现象,终端手机在这些模三干扰小区内会出现时延增高、吞吐量降低、干扰变换剧烈等现象。针对LTE中出现的模三干扰场景进行室内信道重构,从而实现外场无线传输环境的精确模拟。从终端设计角度出发,探索了接收信噪比、调制编码方式选择、天线增益平衡性对终端平均接收吞吐量的影响,同时给出终端设计建议。The drive test data of terminals show that there are plenty of mode-3 interference phenomena in the cellular wireless network, which causes terminals in the mode-3 interference cells to experience increased delay, reduced throughput, sharp interference changes, etc. For the mode-3 interference scenarios in LTE, the indoor channel reconstruction is established to accurate simulate the field wireless propagation environment. From the perspective of terminal design, this paper explores the impacts of the received signal-to-interference-plus-noise ratio, modulation and coding scheme selection, and the balance of antenna gain on the average received throughput of terminals. Meanwhile, the recommendations are given for the terminal design.
