    • Interference cancellation in a mobile terminal (4) in telecommunication systems like Direct Sequence - Code Division Multiple Access systems or DS-CDMA systems can be improved by providing the mobile terminal (4) with a multi-user detector (41,42,43). These multi-user detectors require the spreading codes of other mobile terminals (2,3,5,6,7,8,9), which spreading codes are available in base stations (1) and thus need to be sent to said mobile terminal (4). By further transmitting power information of other mobile terminals (2,3,5,6,7,8,9) to the mobile terminal (4), a selector (52) can make an intelligent selection in said mobile terminal (4) and select the most important spreading codes thereby reducing the computational complexity. By locating a selector (22) in a base station (1), an intelligent selection can also be made in said base station. Preferably a selection is made per antenna sector and/or in dependence of antenna sectors, in which case direction information of other mobile terminals (2,3,5,6,7,8,9) need to be used.

    • The present invention discloses an axial flow impeller comprising a hub and at least three base blades mounted around the hub evenly, in which the base blades are capable of doing work on an external object, and a cover blade is detachably mounted in the front and/or rear of each base blade. When the axial flow impeller of the present invention is applied in a medium environment having a high density and viscosity, it will meet the requirement only by virtue of the base blade with the cover blade being removed; when the axial flow impeller of the present invention is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the axial flow impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the axial flow impeller of the present invention can be adaptable to different medium environments and efficiency requirements, and thus the axial flow impeller can have good adaptibility, need minimal investment cost and can be convenient to use.
    • 本发明公开了一种轴流式叶轮,该轴流式叶轮包括轮毂和至少三个基座叶片,所述基座叶片均匀地围绕所述轮毂安装,其中所述基座叶片能够对外部物体进行作业,并且盖叶片可拆卸地安装在所述前部和/ 或每个基础刀片的后部。 当本发明的轴流式叶轮应用于具有高密度和高粘度的介质环境中时,只有在基体叶片被移除的情况下才能满足要求; 当本发明的轴流式叶轮应用于具有低密度和低粘度的介质环境时,盖叶片可以安装在基叶片的前部和/或后部,以提高轴流式叶轮的效率。 在这种情况下,可以在产生相等的推进力的同时显着降低电力消耗,从而有利于节能。 因此,本发明的轴流式叶轮可以适应不同的介质环境和效率要求,从而使轴流式叶轮具有良好的适应性,投资成本最低,使用方便。
