IEEE Journal on Selected Areas in Communications Volume 19 N°8 Special issue on Multiuser Detection techniques
We derive a low-complexity receiver scheme for joint multiuser decoding and parameter estimation of CDMA signals. The resulting receiver processes the users serially and iteratively, and makes use of soft-in soft-out single-user decoders, of soft interference cancellation and of expectation-maximization parameter estimation as he main building blocks.
Computer simulations show that the proposed receiver achieves near single-user erformance at very high channel load (number of users per chip) and outperforms onventional schemes with similar complexity.
