摘要
Abstract
Multiple RRU cascade networking in the same cell can reduce cell handover in high-speed railway, however, because of Doppler effect, UE may receive two signals with two different frequencies and its demodulation function is severely affected, leading to drop call and low throughput rate. These are usually emerged in some WCDMA mobile phones with non-Qualcomm chips. The theory of multiple RRU cascade networking in the same cell and drop call problems are analyzed, in addition, the advice and solutions are proposed.关键词
