摘要： The present invention discloses a method for code channel allocation and related multiuser detection in a wireless communication system. The method for code channel allocation includes: establishing a relation between at least one channel estimation window and a channelization code, wherein the at least one channel estimation window corresponding to the channelization code includes the channel estimation windows corresponding to all the spread spectrum code branches of a node in which the channelization code exists; and performing code channel allocation according to the relation established. In the method for code channel allocation of the invention, there exists a one-to-many relation between the channelization code/channelization code number established and the at least one channel estimation window. Therefore, during the multiuser detection, the channelization code/channelization code number determined via the at least one channel estimation window activated is unique. Thereby, the efficiency of the multiuser detection process may be increased.

摘要： An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller 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 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 impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.
