Orthogonal decision-feedback detector for asynchronous multiuser CDMA systems.

Orthogonal decision-feedback detector for asynchronous multiuser CDMA systems.

This paper introduces an asynchronous orthogonal decision-feedback detector (AODFD) for asynchronous CDMA multiuser detection. The AODFD based on entire message-length detection is studied first. A realizable scheme, sliding-window AODFD, is then proposed and its performance is analyzed. In spite of...
