多用户干扰消除方法及基站技术

本发明专利技术公开了一种多用户干扰消除方法及基站，该方法包括以下步骤：基站根据干扰用户的频偏值重构ｍｉｄａｍｂｌｅ干扰信号；以及，基站从接收到的ｍｉｄａｍｂｌｅ信号中消除重构的ｍｉｄａｍｂｌｅ干扰信号，得到消除干扰后的ｍｉｄａｍｂｌｅ信号。本发明专利技术提高了干扰信号重构的准确性，进而提高了后续频偏估计的准确性。

Multi user interference elimination method and base station

The invention discloses a method and a base station multiuser interference cancellation, the method comprises the following steps: a base station according to the user's interference frequency midamble interference signal reconstruction; and eliminating midamble interference signal reconstruction from the received midamble signal in the base station, get rid of the interference signal midamble. The invention improves the accuracy of interference signal reconstruction, and further improves the accuracy of the subsequent frequency offset estimation.
