Symbol-by-symbol based adaptive interference canceller forasynchronous DS/CDMA systems in multipath fading channels

The authors propose a new interference cancellation scheme called the symbol-by-symbol based adaptive interference canceller (SAIC), which adaptively estimates and removes both multiple access interference (MAI) and intersymbol interference (ISI) at the output of the Rake receiver. The SAIC is considerably simpler to implement than existing techniques; computer simulation results demonstrate that it can perform much better than conventional Rake receivers
