Abstract :
A method for adaptively cancelling the multiple-access interference in CDMA systems is addressed. The technique is based on adaptive linear fractional spaced equalisation (LFSE). The simulation results indicate that the LFSE offers significant gains over the conventional detector eliminating the near-far problem without the explicit knowledge of the interfering spreading sequences. Furthermore, LFSE performs despreading and multipath (RAKE) combining with no extra complexity.
