An asynchronous multiuser CDMA detector based on the Kalman filter.

An asynchronous multiuser CDMA detector based on the Kalman filter.

We introduce a multiuser receiver based on the Kalman filter, which can be used for joint symbol detection and channel estimation. The proposed algorithm has the advantage of working even when the spreading codes used have a period larger than one symbol interval (?long codes?), unlike adaptive equa...
