摘要：For each user in a multi-user detection arrangement in a CDMA communicationssystem, a detector (80) provides a limiting function (88) responsive to a combined signalto produce a detection signal, having any of at least three possible values, for supply to asignal regenerator, regenerated signals being subtracted from a received signal insuccessive detection iterations of the multi-user detection arrangement. A codecorrelated signal is supplied via an inverse hyperbolic tangent function (84), or ismultiplied by a multiplier inverse to an iteration index, to produce a derived signal. Thederived signal is added (86) to a representation of a detection result stored from aprevious iteration to produce the combined signal. The limiting function can comprise ahyperbolic tangent function.
