Abstract : As a continuation of previous years research on the Bootstrap algorithm, this year's research concentrates on using the F/F bootstrap with the signum function as a discriminator, when it is applied to separation of multiuser CDMA. The performance of this structure was studied and compared with other approaches of signal separation. In addition, research on two new topics was initiated. The first concerns using an adaptive array to improve separator performance. The second, term end "multi-shot separator", is a novel idea that can be implemented for an asynchronous multiuser channel which, in particular, can handle cases wherein the cross correlation matrix is singular.
