LFSE interference cancellation in CDMA systems

Abstract

A method based on linear fractional spaced equalization (LFSE) for adaptively cancelling the multiple access interference in CDMA systems is addressed. 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, it is demonstrated that LFSE performs despreading and multipath (RAKE) combining with no extra complexity.<>
