摘要:
Processing of a received code division multiple access, CDMA, burst (405) when a spreading factor of the CDMA burst (405) has been changed from an allocated spreading factor (SFo) to a new spreading factor (SFn). The received burst (405) is processed with a CDMA detector (310), using the allocated spreading factor (SFo), to provide a CDMA detector output; the new spreading factor (SFn) of the burst is determined; and the CDMA detector output is decimated by a factor determined from the new spreading factor (SFn). The decimator may be a FIR decimator (315) and tap weights may be determined using the values of the new spreading factor (SFn) and the allocated spreading factor (SFo). Application in a Node B (150A) of a UMTS system (100), particularly in UTRA TDD mode, for processing received uplink communication is described.
