| Abstract: | Based on Turbo principle,an iterative multi-user detection receiver structure is proposed for use in convolutionally coded synchronous DS-CDMA systems.The receiver performs successive soft-output decisions,achieved by a soft-in soft-output(SISO) multiuser detector and a bank of channel decoders through an iterative process.Thereby a low-complexity multiuser detection-algorithm,soft MMSE interference cancellation algorithm is obtained. |
