Abstract
Multi-Carrier (MC) Multi-user CDMA is a new transmission method in which every user bit is sent simultaneouslyover mnltiple subcarriers (or multiple tones), each of which has a time-constant 0 or 7r phase offset. The offsets corresponding to each user form a unique code signature sequence, orthogonal to those of any other user, or pseudo orthogonal as with Gold codes or Kessami Code sequences. We address a moderately dispersive channel in which each user-subcarrier channel has a different random amplitude and phase. We estimate the performance of a receiver matched to such a multi-carrier, multi-user scheme. Then we implement a decorrelatinginterference canceler at the output and examine its effect on performance.
