User equipment with multiuser detection
Abstract:
A user equipment (UE) for a wireless time division duplex communication system which uses code division multiple access. The system communicates using communication bursts, each communication burst having a unique channelization code and a midamble code which is uniquely related to the channelization code. Each such midamble code being uniquely related to one or more channelization code. The UE has an antenna for receiving communication bursts and a midamble detector which detects each midamble code in a received communication burst. A logic block determines the channelization codes related to each detected midamble based on a mapping of midamble codes to related channelization codes. A channelization code detector detects channelization codes in the received communication burst from among channelization codes determined by said logic block. A multiuser detection device recovers data from the received communication burst based on in part the channelization codes detected by said channelization code detector. Where all midamble codes are uniquely related to one channelization code, the multiuser detection device recovers data from the received communication burst based on in part the determined channelization codes without the need for the channelization code detector.
