文摘In this paper, a detection strategy based on a semidefinite relaxation of the CDMA maximum-likelihoodmultiuser detection is investigated. Coordinate descent algorithm is used to strengthen the approximation. The simu-lated bit-error-rate performance demonstrates that this approach provides a good approximation to the maximum-like-lihood multiuser detection.
