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.
