给出了一种在CoMP系统中新的两阶段相位调整方法.该方法通过在协作小区对待发送数据流进行相位旋转和相位补偿对小区间传输时延差进行补偿,能在不改变基站发送数据时间、不增加用户复杂度的基础上提升系统的性能.
給齣瞭一種在CoMP繫統中新的兩階段相位調整方法.該方法通過在協作小區對待髮送數據流進行相位鏇轉和相位補償對小區間傳輸時延差進行補償,能在不改變基站髮送數據時間、不增加用戶複雜度的基礎上提升繫統的性能.

A new two stages phase adjustment method in CoMP is proposed. Phase rotation and phase compensation have been ap-plied to the cooperative cel s to compensate the arriving time mismatch. Simulation result shows that this method can bring 2dB gain over the traditional method without changing the transmit time and UE complexity.
